Abstract
A bottom portion is formed on an external end portion of a support sleeve portion 11 which is located on an external side, and an engagement recess is formed in an inner peripheral surface of a support sleeve portion which is located on an internal side. That end face of the engagement recess which faces the support sleeve portion side serves as an engagement surface . An engagement piece is formed on one end portion of a hinge body . The engagement piece is elastically deformed such that its distal end portion is displaced radially inward of the hinge body , thereby the engagement piece is allowed to extend beyond a bottom surface of a key groove . Thereafter, the engagement body is elastically restored such that its distal end portion is displaced radially outward of the hinge body , thereby the engagement piece is engaged with the engagement recess . Then, the engagement piece , when abutted with the engagement surface at its distal end face, prohibits the hinge body from escaping from the support sleeve portion
