Abstract: A steering apparatus whereby the steering load is equal even when the left and right steering angles are large when an outboard motor is steered to the left and right via a swivel shaft. A connecting hole of a steering plate is provided at a position spaced from a center line of the steering plate so that equal angles are formed by a first straight line, joining the center of the swivel shaft and the connecting hole, and a second straight line, joining the connecting hole and a link hole formed in a steering rod.

Abstract: Outboard engine body is mounted via a swivel shaft to a stern bracket. Angle sensor, provided on the stern bracket, includes a contact having a maximum operating angle set to be not greater than half of a maximum steered angle of the engine body, and it outputs detection information indicative of an operating angle of the contact. Curved member is provided on the engine body and normally held in engagement with the contact, and it has a continuously varying radius of curvature from the central axis of the swivel shaft, so that the contact varies in operating angle while sliding along a curved outer peripheral surface of the curved member in response to steering operation. Thus, a steered angle is determined on the basis of the detection information from the angle sensor.

Abstract: A work machine handle device having a foldable handle is disclosed. As the handle is to be changed from a folded-up state to a use state, the handle is turned about a frame as a turning fulcrum. An actuating protuberance provided integrally to a turning member of a clamp body is pushed by a handle engaging/disengaging part provided to a front end of the handle, and the turning member is caused to turn. The handle engaging/disengaging part is held from either side and automatically restrained by a clamp mechanism. When the handle is changed from the use state to the folded-up state, a restraining mechanism is operated to release the engagement between the restraining mechanism and a distal end of the turning member. The turning member is turned by a return force of a spring provided to the clamp body, the handle engaging/disengaging part ceases to be restrained, and the handle can be folded up.

Abstract: A work machine handle device includes a handle foldable relative to a frame. The frame has a handle support part about which the handle turns. The handle intersects the handle support part. Left and right attachment parts, which are portions where the handle intersects the handle support part, are supported by a handle turning mechanism with suitable pressure.

Abstract: In an outboard motor shift control system to change the shift position by controlling the supply of current to an electric shift motor for driving a shift mechanism, a detent mechanism is equipped for constraining the operation of the shift mechanism and holding the shift position once the shift position has been established, and the supply of current to the shift motor is discontinued upon detection that the shift position has been established. This configuration makes it possible to minimize the power consumption of the shift motor and ensure secure holding of the established shift position.

Abstract: An outboard motor steering system includes a hydraulic fluid supply mechanism connected to the steering hydraulic cylinder to supply hydraulic fluid thereto disposed in a space formed between the stern brackets and the swivel case. In other words, since the hydraulic fluid supply mechanism is incorporated into the outboard motor as a unit, the structure can be made simpler than that of the related art and the number of parts in the entire system can be reduced and moreover the work of installation into the boat's hull can be simplified. Also, operating efficiency is improved for an electric motor serving as the source of driving force for a hydraulic pump that supplies hydraulic fluid to the hydraulic cylinder used for steering, and power consumption is reduced.

Abstract: In an outboard motor control system, a position of a clutch (moved by an actuator) is memorized as a neutral position when a neutral switch produces an ON signal and the clutch position corresponding to a forward position where the clutch engages with a forward gear or a reverse position where the clutch engages with a reverse gear is determined based on the memorized position. With this, the clutch can be accurately shifted to the positions where the forward, neutral and reverse shift positions are established, thereby preventing shifting errors. Similarly, by memorizing rudder angle sensor outputs when the outboard motor is mechanically stopped by left and right steer stops as maximum leftward or rightward rudder angles, desired values for control purposes when steering the outboard motor to the maximum rudder angles can be determined as values that take the unit-specific properties of the outboard motor into account.

Abstract: In an outboard motor steering control system having a plurality of outboard motors each mounted on a stern of a boat by a shaft to be movable by an outboard motor actuator relative to the boat and each having an internal combustion engine and a propeller powered by the engine to propel the boat, a tie-bar motor (actuator) is operated such that the outboard motors can be finely operated synchronously to make desired steering angles finely, i.e., to achieve the desired steering angles in response to a detected rotation angle of a steering wheel. Also outboard motor actuators are individually operated to regulate the relative angles between the outboard motors, thereby enhancing both straight course-holding performance and turning performance.

Abstract: In an outboard motor, an extension case (member constituting a frame of the outboard motor) has the natural frequency (resonance frequency) of higher than the vibration frequency produced when the engine operates at maximum speed. Since this configuration prevents the extension case from resonating during operation of the outboard motor, noise (more specifically, noise produced by the outboard motor) propagated to the outside can be reduced.

Abstract: In a boat having a seat, a steering wheel, and an outboard motor, an outboard motor steering system is provided, where the steering wheel is installed near the seat a steering angle sensor installed near the steering wheel for outputting a signal indicative of a steering angle of the steering wheel. The steering system also includes a swivel shaft connected to a propeller to turn the propeller relative to the boat, and an electric motor connected to the swivel shaft for rotating the swivel shaft in response to the detected steering angle. The steering system also includes a manipulation load regulation mechanism, such as a hydraulic damper, to produce an added load for increasing a manipulation load of the steering wheel, thereby enabling reduced operator load by using the electric motor to steer the outboard motor, while improving the operator's feel of steering wheel manipulation.

Abstract: In an outboard motor control system equipped with an electric throttle motor for moving the throttle valve of the engine mounted on the outboard motor, an electric shift motor for operating the shift mechanism to establish one from the in-gear, neutral and reverse shift positions, and a low-speed cruising switch for inputting the instruction to implement a low-speed cruising for causing the boat to cruise at a low speed, when the instruction is inputted, a throttle control is effected by controlling the operation of the motor to a set throttle opening and shift control is effected by controlling the operation of the motor to establish the in-gear position and neutral position alternatively, thereby enabling to cruise over a wide range of speeds including very slow, without requiring troublesome manual operations.
