  • Patent number: 11964631
    Abstract: There is provided a damper device including an annular elastic member made of an elastic resin material. One member of a pair of members is provided with a support section for supporting the annular elastic member. The other member of the pair of members is provided with a pair of facing walls between which the support section is to be inserted. The annular elastic member is provided with separated portions that are separated from the outer periphery of the support section. In a state where the annular elastic member is mounted on the outer periphery of the support section, a maximum distance A of the separated portions facing each other is greater than an opening width B between tip ends of the pair of facing walls on a side on which the support section enters.

  • Publication number: 20240044189
    Abstract: There is provided a lock device for an opening and closing body, including: a locking portion; a locking member; a case including a first case and a second case; a rotation body; and a biasing means. A cut-out is provided, and a retaining portion is provided, the retaining portion including a protruding portion and being configured to retain the rotation body relative to the first case. A first engaging surface and a second engaging surface are configured to engage with each other to form a temporary locking portion for temporarily locking the rotation body. A cam means and a stopper are provided between the second case and the rotation body, the stopper being configured to engage with the rotation body so as to hold the rotation body with the first engagement surface and the second engaging surface disengaged from each other.

  • Publication number: 20230278502
    Abstract: There is provided a locking device for an opening and closing body, including: a locking portion; a base; a rotation body that includes a protruding portion on a part of an outer periphery thereof; a locking member; and an elastic member that includes a base portion, and a stopper portion configured to restrict a maximum rotation position of the rotation body in a predetermined direction by abutting against the protruding portion of the rotation body. The stopper portion is disposed in a manner of being biased in a direction opposite to the predetermined direction relative to the base portion. A part of the outer periphery of the rotation body is provided with a sliding contact portion that is configured to come into sliding contact with the elastic member in a process in which the protruding portion approaches the stopper portion.

  • Patent number: 9803604
    Abstract: In a mounting tool for mounting an injector on a cylinder head of an engine by being engaged with the injector connected to a fuel pipe, and urging the injector toward the cylinder head, a first band portion has a ring shape so as to surround an outer circumference of the injector, and is disconnected in a circumferential direction by a slit. A second band portion has a ring shape so as to surround the outer circumference of the injector, is disconnected in the circumferential direction by a slit, and is arranged adjacent to the first band portion in an axial direction. Plural elastic band portions connect the first band portion and the second band portion in the axial direction. The mounting tool is made of a single metallic plate.
