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.
Claims14
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 that is a separate and discrete part from the allowing member and 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 means mountable on the pair of holding portions for coupling together the regulating member and the allowing member into a subassembly, wherein the urging means retains a side of the regulating member against a side of the allowing member by applying a retaining force along a direction which is substantially orthogonal to the direction that the urging means biases the regulating member.

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 that is a separate and discrete part from the allowing member and 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;
- an urging means mountable on the pair of holding portions for coupling together the regulating member and the allowing member into a subassembly, and a fitting portion that allows the allowing member and the regulating member to fit with each other such that the allowing member and the regulating member are relatively rotatable,
- wherein the regulating member and the allowing member are rotatably supported by a shaft, and the shaft penetrates the pair of holding portions, and the fitting portion is formed at at least one of the regulating member and the allowing member and is coaxial with the shaft.
