  • Patent number: 11383045
    Abstract: A stopper being adapted to be fixed in a rear end portion of a syringe is provided. The stopper is reduced in diameter at a fitting portion of a rod portion of a plunger rod so as to have a diameter smaller than an inner diameter of the rear end portion and be insertable into the rear end portion. After insertion, the stopper is increased in diameter and is fixed in the rear end portion so as not to be movable in an axial direction by fitting a first recessed portion on a periphery into a second protruding portion of an inner surface of the rear end portion. The stopper has, on an inner surface, a third protruding portion having an inner diameter smaller than an outer diameter of a gasket support flange of the rod portion in a fixed state.

  • Patent number: 11353109
    Abstract: A range switching device for switching between a plurality of shift ranges in a vehicle. In the range switching device, the shift ranges are switched depending on a rotational angle of a detent plate that has (i) a first engaged portion for maintaining an angle value of the rotational angle of the detent plate by which a parking range as one of the shift ranges is established in the vehicle and (ii) a second engaged portion for maintaining another angle value of the rotational angle of the detent plate by which a reverse running range as another one of the shift ranges is established in the vehicle. The first and second engaged portions are located in respective positions adjacent to each other in a circumferential direction about a rotational axis about which the detent plate is to be rotated.
