    • Working-machine steering apparatus includes an assist mechanism for reducing a force necessary for operating any one of left and right operating members. First and second cord members, connected to the left and right operating members, are wound on first and second pulleys in a U shape with given pre-slack. As a human operator operates any one of the left and right operating members, the corresponding left or right cord member is brought into close contact with the first or second pulley, so that rotation of a drive source is transmitted to the first or second pulley via a rotation shaft. The necessary operating force of the left and right operating members can be reduced using the rotation of the drive source via the assist mechanism.

    • In a clutch mechanism, a disc-shaped friction plate is disposed in a housing and an oil seal is interposed between an inner circumferential surface of the housing and the outer circumferential surface of the friction plate. The oil seal applies an inward radial force to the friction plate which, when the friction plate starts to rotate, gives rise to a circumferential frictional force tending to prevent the friction plate and a plurality of clutch pins fitted in pin-holding grooves formed in an inner circumferential surface of the friction plate from moving. Consequently, a stable frictional force is obtained between the housing side and the friction plate. Because the force providing the friction acts in the radial direction of the friction plate, no spring for providing an axial thrust is required and the length direction dimension of the driving member can be made small and the clutch mechanism can be made compact.
    • 在离合器机构中,盘形摩擦片设置在壳体中,并且油封被插入在壳体的内周面和摩擦片的外周面之间。 油封向摩擦板施加向内的径向力,当摩擦片开始旋转时,摩擦片产生周向摩擦力,以防止摩擦片和多个离合器销装配在形成于 摩擦板的内周面从移动。 因此,在壳体侧和摩擦片之间获得稳定的摩擦力。 由于提供摩擦力的作用力在摩擦板的径向方向上,因此不需要用于提供轴向推力的弹簧,并且可以使驱动构件的长度方向尺寸变小并且使离合器机构紧凑。
