Abstract
A regulating member, an allowing member and an urging member are easily assembled to a subject to which these members are assembled. When assembling of an interlock unit is carried out, with a fitting convex portion of a link being fitted into a fitting concave portion of a release link, a torsion spring (particularly, a connecting portion) is temporarily elastically deformed, and a pair of spiral portions of the torsion spring are mounted to spring holding shafts of the link and the release link, respectively. As a result, the link, the release link and the torsion spring can be brought into a temporarily assembled state, and can be easily assembled to a unit box.
Claims13
A key device comprising:
- a rotating member that is rotated by rotation of a key;
- an allowing member that is rotated by the rotating member when the rotating member is rotated to a predetermined rotational position;
- a regulating member disposed at one side of the allowing member, that regulates rotation of the rotating member to the predetermined rotational position by not being rotated together with the allowing member when the rotating member is rotated to the predetermined rotational position, and that allows rotation of the rotating member to the predetermined rotational position by being rotated together with the allowing member when the rotating member is rotated to the predetermined rotational position;
- a pair of holding portions that protrude toward another side of the allowing member and toward one side of the regulating member, respectively;
- and
- an urging member having urging force, that causes the allowing member and the regulating member to be assembled by being held by the pair of holding portions.
