The winding housing includes a spring tab that is spaced from the central axis. The recoil starter also includes a spirally wound spring having an outer end portion that is coupled to the heel, a coiled portion that extends around the central axis, a guide portion that extends between the central axis and the spring tab, and a hook portions that extends radially outwardly from the central axis and that engages the spring tab to restrict movement of the inner end with respect to the winding housing.

Abstract: A rotary cutter for a mower capable of limiting the reeling out of a cord, when the free end of the cord is worn out to only when the rotary cutter is rotated at low speed thereby preventing pebbles or the like from being scattered. The rotary cutter is disengaged without the component parts being separated thereby facilitating reassembly. The rotary cutter includes a cord for mowing grass on being rotated, a reel for containing the cord and reeling out the cord intermittently while being rotated, a cover covering a case containing the reel, and a plunger projected downward from the case and movable in an axial direction by being pressed for intermittently rotating the reel. A ratchet is held at a constant position by an urging element which is moved outward to open against the direction of the urging element by the centrifugal force produced by rotating the rotary cutter at a high speed and is engaged with the plunger to thereby prevent the plunger from moving in the axial direction.

Abstract: A rotary cutter for a mower is provided wherein the cord delivering operation, which is necessary when the free end of the cord is worn, is carried out only when the rotary cutter is rotated at a low speed or is stopped. The rotary cutter includes a cord for cutting grass upon rotation thereof, a reel which holds the cord and allows delivering of the cord while the reel is intermittently rotated, a cover for a case which houses the reel, and a press body which protrudes downwardly from the case and is movable in an axial direction upon pressing so as to intermittently rotate the reel. A return spring for biasing the press body in a direction to protrude the press body from the case between the reel and the press body is also provided. The press body and the case engage each other such that the press body is slidable in an axial direction while preventing relative rotation with each other.

Abstract: An engine starting device includes a self-starting motor drivable to rotate the crankshaft of an engines, and a one-way clutch operable to permit transmission of rotary motion of the self-starting motor in one direction only to the crankshaft. The one-way clutch includes an inner race operatively connected to an output shaft of the self-starting motor, an outer race operatively connected to the crankshaft, a plurality of ratchet pawls pivotally connected to the inner race and urged by springs against the inner race. The one-way clutch is designed such that, when the speed of rotation of the inner race while being rotated by the self-starting motor goes up to a predetermined value, the ratchet pawls are caused to swing in a radial outward direction under the action of centrifugal force against the bias of the springs and become engaged by the outer race to thereby engage the one-way clutch.

The first one-way clutch includes a small gear, a decelerating gear and a large gear. The small gear is connected to the crankshaft and has step portions on an inner peripheral surface thereof. The decelerating gear is connected to an output shaft of the starter motor. The large gear is connected in meshing engagement with the decelerating gear and has ratchets urged to mesh with the step portions of the small gear to engage the first one-way clutch only when the large gear is rotated via the decelerating gear upon rotation of the starter motor in such a direction as to start an engine.

Abstract: An engine starting apparatus comprises a case having an outer case and a case cover defining an interior space. The outer case has at least first, second and third bolt apertures, for attaching the case to an engine.

A recoil starter mechanism is disposed in the interior space of the case for starting the engine. The recoil starter mechanism has a starting rope pulling port disposed adjacent to the first bolt aperture. The starter motor is disposed between the first bolt aperture and the third bolt aperture when the starting rope pulling port is positioned between the first bolt aperture and the second bolt aperture, and the starter motor is disposed between the first bolt aperture and the second bolt aperture when the starting rope pulling port is positioned between the first bolt aperture and the third bolt aperture. First louvers extend from an outer surface of the case cover.

Abstract: There is provided a recoil starter for starting an internal combustion engine which has a simple and compact structure with a reduced number of parts and which can be manufactured at a reduced cost.

Abstract: A recoil starter is provided which prevents malfunction, such as disengagement of a claw, after the engine is started repeatedly even if the starter is not made of a material of high intensity. A spring can be wound substantially precisely circularly. It is quite easy to mount a friction plate to the starter. Furthermore, this subassembly does not loosen after long-term usage. A rope guide can be easily mounted to the starter case, thus reducing the fabrication cost. The recoil starter can be placed and locked in position relative to a fan cover with high accuracy. When the ratchet is in its protruded position, the pivotal point of the ratchet is located radially inside a pulley around the position where the pulley engages the ratchet. A ratchet support portion is formed radially outside the pulley on the reel. The ratchet forms a beam supported at its both ends. The beam acts against a force exerted by the pulley due to a resistance produced when the engine is started.

Abstract: A recoil starter casing is made from a plate. The plate has a polygonal top face and a plurality of rectangular side faces integral with and extending from respective edges of the top face. Each of the side faces includes a recess in its edge, and a pair of projections at opposite ends of the recess. A plurality of air inlets are formed in the side faces. The side faces are bent from the top face along the respective edges of the top face. A fan cover has slots. The projections are inserted into the corresponding slots. The free ends of the projections are then bent so as to secure the starter casing to the fan cover. The inside of the starter casing is cooled through the air inlets and the recesses or air vents.

Abstract: A remote control device applicable to an electronic apparatus provided with a power supply voltage stabilizing unit of switching type for the on-off control of power supplied to the electronic apparatus. The device comprises an electronic switch including a single thyristor or a plurality of transistors controlled by a remote control signal. The circuit operation of at least one of circuits constituting the power supply voltage stabilizing unit is disabled by turning on the electronic switch thereby stopping the power supply to the electronic apparatus, and when the electronic switch is turned off, the circuit operation is restored to restart the power supply to the electronic apparatus.

Abstract: A make-type contact of a relay-type member and a manual switch are connected between a commerical A.C. power supply and a load circuit. The manual switch is turned on only when it is being manually actuated and turned off when it is not manually actuated. A winding of the relay is connected to the load circuit such that an excitation current flows therethroiugh through the load circuit or a control unit, and it is also connected to the control unit for receiving signals from a remote control unit. When the manual switch is turned on through manual actuation, a power is supplied to the load circuit or the control unit to excite the winding-type portion so that the make-type contact is closed to hold the power to the load circuit even after the turn-off of the manual switch. When the control unit, on the other hand receives the signal from the remote control unit the winding-type portion is deenergized to stop the supply of the power to the load circuit.
