    Abstract: A stop mechanism (23) of a helm device (16) includes a rotation member (80) which can be relatively rotated with respect to a steering shaft (22), rotatable disks (81), fixed disks (82) opposed to the rotatable disks (81), and an electromagnet (83) which presses these disks (81, 82) against one another. An inversion control pin (110) is provided in the steering shaft (22). Slits (120) are formed in a cylindrical portion (80a). Both ends of the inversion control pin (110) are inserted into the slits (120). The slits (120) are shaped to be elongated in a circumferential direction of the cylindrical portion (80a). A first pin receiving stopper wall (121) is formed on one end of the slits (120). A second pin receiving stopper wall (122) is formed on the other end of the slits (120). The inversion control pin (110) can move within the range of inversion allowance angle (¸) between the pin receiving stopper walls (121, 122).

    Abstract: A knee-action-type suspension (11) is provided with an arm member (20), a compression coil spring (21), and a shock absorber (24). The arm member (20) is supported in such a way that it is pivotable in the upward and downward directions by a pivot (31) provided on an arm mounting portion (30). The coil spring (21) is arranged between spring seats (22, 23). The coil spring (21) is extended and retracted between a full-rebound state and a full-bump state in accordance with the magnitude of a load applied to a vehicle body. A wire (40) of the coil spring (21) includes a large-diameter wire portion (40a), a small-diameter wire portion (40b), and a wire diameter varying portion (40c). The large-diameter wire portion (40a) is provided in a first portion (21a) of the coil spring (21), which is on the side near to the pivot (31). The small-diameter wire portion (40b) is provided in a second portion (21b) of the coil spring (21), which is on the side far from the pivot (31). A wire diameter (d1) of the large-diameter wire portion (40a) is greater than a wire diameter (d2) of the small-diameter wire portion (40b).

    Abstract: An accumulator (1) includes a bellows (5) housed to freely expand and contract in a shell(2), a port part (6) having a pressure fluid inflow port (61) formed therein, and a self-sealing member (8) arranged on a tip portion of the bellows to face the port part, in which, when a pressure in the fluid chamber (4) is lower than a predetermined pressure relative to an air chamber (3), the self-sealing member is allowed to abut onto a seal area (SA) of the port part to block the pressure fluid inflow port. The self-sealing member includes a resilient member (82) arranged on a surface of a base material part (81), and an overhanging portion (83) formed on the resilient member and allowed to abut onto the seal area for sealing. The port part includes a seal face (63a) having the seal area formed thereon, and a projecting portion (64) arranged on a region other than the seal area on the seal face.
