Further, on the bottom surface of the rod portion 2b, there is provided a concave groove having a small width in a direction orthogonal to the rod portion 2b over substantially the entire surface except for both ends, and a ridge between the grooves is provided to make a sliding movement in the width direction of the belt contacting this surface. It is an uneven surface 7 that prevents

Further, the inner surface of the rod portion 2b is chamfered to prevent the lower end edge from coming into strong contact with the belt.

At the central portion of the rod portion 2a, an engaging portion 5 having a notched upper surface and an outer surface with a constant width is provided for the end portion of the locking rod 3 to engage, and the engaging portion 5 has a bottom surface at the bottom surface. A cutout groove 5a is provided along the outer edge.

Further, a receiving portion 6 of the locking rod 3 is provided on the inner surface of the engaging portion 5, and a receiving groove 6a having a rectangular cross section is provided in the receiving portion 6 in a direction orthogonal to the rod portion 2a. The upper surface of 6 is a downward slope facing the receiving groove 6a.

The locking rod 3 has a thin plate shape, and both end portions 3a, 3a are made thin so that they can be elastically deformed and bent downward at a substantially right angle. Claws 3b, 3b
Is provided. Further, a rib 3c having a rectangular cross section along the center line is provided on the lower surface of the locking rod 3 in the center in the width direction, and the end of the rib 3c and the bent end 3a of the locking rod 3 are provided. A gap is provided between the inner surface and the inner surface for receiving the engaging portion 5 of the frame 2. The upper surface of the locking rod 3 is an uneven surface 7 similar to the bottom surface of the rod portion 2b, and the lower surface is inclined from both sides toward the side surface of the rib 3c and the upper surface of the receiving portion 6 of the frame 2. It is an inclined surface, and when the locking rod 3 is attached to the frame 2, the inclined surface is received by the inclined surface on the upper surface of the receiving portion 6.

Therefore, the locking rod 3 has one end 3a engaged with the engaging portion 5 of the rod portion 2a of the frame 2 and the rib 3c fitted into the receiving groove 6a of the receiving portion 6, while the other end portion When 3a is pushed into the engaging portion 5, the claw portion 3b is engaged with the notch groove 5a due to the elastic deformation of the end portion 3a, and the locking rod 3 is assembled to the frame 2, and the upper surface of the locking rod 3 is a rod. The buckle 1 protrudes so that the inclined upper surfaces on both sides of the engaging portion 5 of the portion 2a are connected continuously, and both end surfaces are connected to the outer surfaces of both sides of the engaging portion 5 of the rod portion 2a. It has a smooth shape with no parts.

In this buckle 1, the auxiliary belt B is passed through the long hole 4 and the shoulder belt A is attached to the bottom surface side of the rear frame 2 after being attached, in a direction orthogonal to the rod portion 2b, and the shoulder is located between the rod portions 2b and 2b. While slackening the portion of the belt A, the belt A is pulled into the frame 2 and pulled out to the upper surface of the frame 2. And this shoulder belt A pulled out
