  • Publication number: 20220307590
    Abstract: In this shift device, in a case in which an external force has acted on a lever when an operating mechanism is causing the lever to pivot, a clutch mechanism permits rotation of a first detent plate with respect to a second detent plate, such that pivoting of the lever is permitted. Note that a restraining mechanism urges the lever toward a shift position. This enables to the restraining mechanism to urge the lever separately to the clutch mechanism, thereby enabling the degrees of freedom for setting a biasing load on the lever by the restraining mechanism to be increased.

  • Patent number: 11215258
    Abstract: A hydraulic shock absorber includes: a cylinder; a piston rod on which a first piston, a valve, and a second piston are disposed sequentially from one end side; and an oil lock portion that is disposed on the one end side inside the cylinder, and that forms a gap flow path between the oil lock portion and an outer circumferential surface of the first piston. The first piston has a piston internal flow path, and is displaceable in an axial direction of the piston rod. When the piston rod moves toward the one end side, the first piston relatively moves toward the other end side with respect to the piston rod and the other end side of the first piston abuts against the valve, so that due to a flow of working oil passing through the piston internal flow path, the valve bends to generate damping force.
