Abstract: A clip has a base portion embedded in a seat body and two locking portions formed on an upper surface of the base portion. The locking portions are arranged longitudinally in a front-rear direction on the upper surface of the base portion, and each locking portion is composed of a pair of locking piece portions extending upward and facing each other. Each locking piece portion has an extension portion connected to the upper surface of the base portion and a claw portion connected to an upper end of the extension portion. One of the locking piece portions is a one-sided locking piece portion, and the other is an elastic locking piece portion. An elastic force of the elastic locking piece portion is smaller than that of the one-sided locking piece portion, and therefore the elastic locking piece portion is more easily elastically deformed than the one-sided locking piece portion.

Abstract: A rotation member is divided into a first detection region and a second detection region. A first interval in the circumferential direction between the detection target located at the tail end of the first detection region in the main rotation direction and the detection target located at the front end of the second detection region in the main rotation direction is less than a second interval in the circumferential direction between the detection target located at the tail end of the second detection region in the main rotation direction and the detection target located at the front end of the first detection region in the main rotation direction.

Abstract: A fastener includes a fitted portion having an elastic piece that is disposed on a side of a base portion configured to allow insertion of the fitted portion into a through hole by elastic deformation in a direction of approaching a base portion and to engage the through hole at an insertion point of the insertion by elastic return in an end position of the insertion, and that is configured to, if force in a direction of pulling out the fitted portion from the through hole is applied, cause the elastic deformation in the approaching direction. The base portion includes an abutting portion abutting on the elastic piece if the force in the pulling-out direction is applied, and, if the force in the pulling-out direction is equal to or greater than a predetermined magnitude, the elastic piece bends in a direction toward a central axis of the fitted portion.

Abstract: A tilted surface is provided in a heating unit and is tilted with respect to a first direction. A movable member includes a roller and is movable along the first direction. A first direction movement mechanism causes the movable member to move along the first direction in an interlocking manner with a movement of an operation member. When the movable member moves in an interlocking manner with the movement of the operation member in a first operation direction, the roller rolls on the tilted surface to cause the heating unit to move toward a second side against a bias force of a bias member. When the movable member moves in the interlocking manner with the movement of the operation member in a second operation direction, the roller rolls on the tilted surface, and the bias member causes the heating unit to move toward a first side.

A first interval in the circumferential direction between the detection target located at the tail end of the first detection region in the main rotation direction and the detection target located at the front end of the second detection region in the main rotation direction is less than a second interval in the circumferential direction between the detection target located at the tail end of the second detection region in the main rotation direction and the detection target located at the front end of the first detection region in the main rotation direction.

Abstract: A movable member includes a second engagement portion that is engaged with a first engagement portion of a drawing port cover at a reference position when the drawing port cover is closed. One of the movable member and the drawing port cover has a slide surface. The other of the movable member and the drawing port cover includes a contact portion. In the process of the movement of the drawing port cover to a closed position, the movable member is moved to a retraction position by force applied by the contact portion sliding on the slide surface. When the drawing port cover is located at the closed position, the movable member is held at the reference position by biasing force of the second-direction biasing member and the drawing port cover is held at the closed position by engagement between the first engagement portion and the second engagement portion.
