Abstract:
A buckle device which is disposed at a seat in a vehicle, and into which a tongue plate, which is attached to a webbing for restraining a vehicle occupant, is inserted, the buckle device comprising:a buckle member having, at an upper portion of the buckle member, a buckle into which the tongue plate is inserted, and having, at a lower portion of the buckle member, a linking portion in which an elongated hole is formed along a vertical direction of the vehicle and in which a retaining portion is formed at one of an upper side and a lower side of the elongated hole; a supporting member which is fixed within the vehicle so as to correspond to the buckle member, and provided with a rotating shaft which is inserted through the elongated hole of the linking portion, the linking portion being supported so as to swivel around the rotating shaft such that the buckle member can swivel, and the rotating shaft being movable between an upper end and a lower end of the elongated hole, so that the supporting member supports the buckle member slidably; an abutment portion which is provided at the supporting member, and which abuts the buckle member and prevents swivel of the buckle member in a state in which the buckle member is at a swiveling position at which the buckle member stands; a spring member having a torsion coil spring and a compression coil spring, the torsion coil spring having a helical spring portion, the rotating shaft being inserted through an interior of the spring portion, the compression coil spring being formed in a helical shape, one end of the compression coil spring being retained at the retaining portion, and another end of the compression coil spring being linked to a first end portion of the torsion coil spring, and the compression coil spring applies urging force to the buckle member and makes the rotating shaft abut the lower end of the elongated hole; an engagement portion which is provided at the supporting member, and due to a second end portion of the torsion coil spring engaging with the engagement portion, the torsion coil spring applies urging force to the buckle member and makes the buckle member abut the abutment portion; and a case member which is provided so as to accommodate the compression coil spring, and which prevents buckling which accompanies compression of the compression coil spring.
