  • Patent number: 11472370
    Abstract: In an anchor device, when a pin restriction portion of a spring plate moves so as to ride up over a large diameter portion of an attachment pin, a tilting movement tab of the spring plate undergoes tilting movement, and a cover undergoes tilting movement together with the tilting movement tab. When the plate is moved toward a device length direction one side with respect to the attachment pin and the large diameter portion moves to a device length direction another side relative to the pin restriction portion, the tilting movement tab elastically recovers and the cover returns to its original position. This enables whether or not the large diameter portion has moved to the device length direction another side relative to the pin restriction portion to be confirmed by visual inspection of the cover.

  • Patent number: 11465584
    Abstract: In a webbing take-up device, a moving member is moved while being guided along a cylinder in order to rotate a spool in a take-up direction. A urging plate of a guide member urges a flange at an axial direction leading end portion of the cylinder toward a restricting direction side, and a leg plate of a frame restricts rotation of the flange toward the restricting direction side. This enables rattling of the axial direction leading end portion of the cylinder about the axial direction of the cylinder to be suppressed.

  • Patent number: 11441674
    Abstract: A strength of an outer side portion in a second direction of a shift body is increased. In a shift device, when a lever is placed in an ‘M’ position, a right avoidance hole of the lever avoids interference with a right restricting portion, rotational movement of a left restricting surface of the lever is restricted by a left restricting portion, and an operation to rotationally move the lever towards the right side is restricted. Furthermore, when the lever is placed in a ‘D’ position, a left avoidance hole of the lever avoids interference with the left restricting portion, rotational movement of a right restricting surface of the lever is restricted by the right restricting portion, and an operation to rotationally move the lever towards the left side is restricted. The right avoidance hole and the left avoidance hole can be made smaller, so that the strength of both outer side portions in a lateral directions of the lever can be increased.
