An entrance part 41 of the lock projection, an engaging part 42 with which the lock projection can be engaged, and a cam groove 43 which returns to the entrance part from the entrance part via the engaging part are formed on a surface of the lock tool, and the cam groove is curved in a direction parallel to a slide direction of the lock tool. An upper wall 33 and a bottom wall 34 of the lock tool storage chamber are equipped with a slide regulation part of the lock tool, and the lock tool is equipped with a follower which slidably contacts the slide regulation part. The slide regulation part is at least one strip of continuous bulge part 35 which extends in parallel to the slide direction of the lock tool, the follower is at least one projection 46, and the projection slidably contacts a lateral face of the continuous bulge part.SELECTED DRAWING: Figure 2 |
