Abstract

The invention relates to a belt buckle connecting a seat belt. The belt buckle can prevent the connection state of the seat belt from becoming loose and can push out a male component from an insertion port of a female component reliably in removing the connection state. A locking component (40) is provided with a removal button (90) facing to an opening (32) arranged in the female component (30). The removal button is pressed in by exerting forces to the opening and overcoming the acting force, thereby removing the cooperation state of a fitting part (100) and a snapping part (80). Either of the fitting part and the snapping part is provided with a press spring (102) arranged to abut against the other one, bending for force accumulation and pushing out an insertion sheet (60) of the male component (20) from the insertion port (31) of the female component through accumulated elasticity under a cooperation state of the two part (80, 100); and a retaining part (101) clamping the other one together with the press spring.

Description

technical field [0001] The present invention relates to a buckle for connecting seat belts, and more particularly to a buckle capable of preventing loosening of the connection state of the seat belt and reliably pushing out a male part from an insertion opening of a female part when the connection state is released . Background technique [0002] Conventionally, there is known a buckle in which a release button is slidably supported in the hollow interior of a female member, and a claw portion of the release button is inserted into a locking hole of a male member inserted from an insertion port of the female member (for example, refer to the patent document The paragraph numbers of 1 are 0047, 0051, 0057, figure 1 and Figure 8 ). [0003] Patent Document 1: Japanese Patent No. 4302038 [0004] However, in the above-mentioned conventional buckle, the claw portion of the release button is simply inserted into the locking hole of the male member, so there is a problem that...
