  • Publication number: 20240048027
    Abstract: A reciprocating tool includes a motor, a reciprocating member, and a crank mechanism. The motor is disposed in a housing. The reciprocating member projects from the housing. The crank mechanism converts rotation of a rotation shaft of the motor into reciprocation of the reciprocating member. The crank mechanism rotates around an axis in a lateral direction by rotation transmission from the rotation shaft, and the crank mechanism includes a crank member having an eccentric pin, a connecting rod coupling the eccentric pin to the reciprocating member, and a balancer coupled to the eccentric pin, and the balancer is supported by the eccentric pin alone in the housing.

  • Publication number: 20230264798
    Abstract: A propulsion device for a marine vessel includes an engine and a forward/reverse shifting mechanism. The direction of a propulsive force generated by the propulsion device is changed according to a shift position of the forward/reverse shifting mechanism. The shift position is changeable between a forward position and a reverse position via a neutral position. In response to a command signal based on an operation of a joystick or an operator, the shift position of the forward/reverse shifting mechanism and the engine are controlled. When the shift position of the forward/reverse shifting mechanism is changed from the neutral position to a position corresponding to a direction opposite to a travelling direction of the marine vessel, which is determined based on the speed of the marine vessel, a correction control is performed to increase an output of the engine based on the speed of the marine vessel.

  • Publication number: 20220315190
    Abstract: A marine propulsion device includes a first gear, a second gear, a third gear, a case, a partition wall, and a first flow path. The case includes an internal space in which the first gear, the second gear, and the third gear are located. The partition wall is located between the second gear and the third gear in the internal space. The partition wall partitions the internal space into a first space and a second space. The second gear is located in the first space. The third gear is located in the second space. The first flow path communicates the first space with the second space. The first flow path is located on a same side as the first gear with respect to a center line of the second gear and the third gear.

    Abstract: A dust collector having a filter for catching dust in air flowing in an intake path is provided. A pair of the intake paths are formed so as to be combined together on an upstream side of an electric blower provided in a main body. A pair of communication paths allow a discharge passage to communicate with each of the intake paths. A first opening and closing member is provided so as to open and close the intake path, and in a normal state, is biased to open the intake path. A second opening and closing member is provided so as to open and close the communication path, and in the normal state, is biased to close the communication path, and opens the communication path in response to a closing operation of the intake path by the first opening and closing member.

  • Patent number: 8579485
    Abstract: A vehicular lamp includes a light source disposed on an optical axis extending in a front-back direction of the vehicular lamp; and a reflector that reflects forward light from the light source. The reflector is formed by a translucent member including a plurality of optical elements disposed continuously in a radial direction of the optical axis. Each of the optical elements includes: a surface of incidence through which light from a light emission reference point in the light source is incident into the optical element and which refracts the light into a direction away from the optical axis, a reflective surface which internally reflects forward the light which is incident into the optical element through the surface of incidence, and a surface of emission through which the light internally reflected by the reflective surface is emitted forward from the optical element.
