  • Publication number: 20220161731
    Abstract: A locking device includes a lock portion on one of a fixed body or an opening/closing body, a rod on the other member, and a protrusion protruding from the other member. The rod has a recess surrounded by a pair of first walls facing each other in a sliding direction of the rod and a pair of second walls facing each other in a direction orthogonal to the sliding direction. A first elastic piece extends from one of the first walls toward the other and applies an elastic force against a tip end surface of the protrusion, and a pair of second elastic pieces extend from the second walls. Each of the second elastic pieces has a receiving surface that engages with a back surface of a flange portion of the protrusion, and is configured to elastically abut against a side surface of the protrusion.

  • Publication number: 20220128113
    Abstract: There is provided a damper device including: a cylinder; a piston; and a seal ring. The piston includes: a column portion wound around the seal ring; and a first restricting portion and a second restricting portion that are configured to restrict movement of the seal ring in a axial direction. The column portion has a protruding portion protruding outward in a radial direction. The first restricting portion has a cutout portion. The seal ring is capable of taking a deformed state where the seal ring is deformed so as to partially enter the cutout portion by movement of the piston. In a case where the seal ring is in the deformed state, and in a normal state where the seal ring does not enter the cutout portion, the seal ring is pressed against an inner peripheral surface of the cylinder by the protruding portion.
