And press the small projections 27 provided on both sides to the upper through holes 1.
6, the distal end of the elastic leg 26 is provided on both sides of the lower through hole 11 as shown in FIG.
, And is held in a state in which the tip is slightly expanded, that is, in a state having elasticity, and the operating piece 3 is urged upward to engage the adjusting projection 8 with the locking projection 25. .

The adjustment of the waist adjuster attached to the waist belt 5 is performed by pressing the head 23 of the operation piece 3 inserted into the slider 2 so that the tip of the elastic leg 26 resists the elasticity of the elastic leg 26. Then, the slope 15 is slid and the operation piece 3 is pushed down to release the engagement between the adjustment projection 8 of the adjustment belt 1 and the locking projection 25 of the operation piece 3, and the slider 2 is moved while the operation piece 3 is pressed. After the waist is adjusted by sliding left and right, the pressing of the operation piece 3 is released, and the elastic leg 2 is released.
Due to the elasticity of the operation piece 3, the small protrusion 27 of the operation piece 3
The adjustment projection 8 and the engagement projection 25 are engaged with each other to return upward until they come into contact with the edge of the waist, thereby completing the adjustment around the waist.

The waist adjuster of the second embodiment shown in FIGS. 10 and 11 is an improvement of the waist adjuster of the first embodiment in the form of a slope 15 provided on both sides of the lower through hole 11 installed in the slider 2 in the waist adjuster of the first embodiment. In addition, the form is such that the slope portions 1 arranged on both sides of the lower through hole 11 of the slider 2.
5, a small projecting piece-like side wall 18 is protruded upward at a position located on the side of the surface plate 12 to form a concave groove 19 in which the cross-sectional shape of the inclined surface 15 is concave. By sliding the distal end of the elastic leg 26 provided on the slide member 3 and sliding the elastic leg 26, the elastic leg 26 is prevented from falling off from the slope portion 15, and the elastic leg 26 does not rattle and is smoothly moved in a stable state. It is formed so that it can slide.

The waist adjuster of the third embodiment shown in FIGS. 12 to 17 is obtained by improving the slider 2 and the operation piece 3 in the waist adjuster of the first embodiment.
The slider 2 is, as shown in FIGS.
On the inner surface of the rectangular through hole 16 provided in the center longitudinal direction, ie, on both side edges on the back side, ridges 20 having a convex cross section are provided so as to extend over the entire length. As shown in FIGS. 14 and 15, the operation piece 3 is provided with a long groove 30 having a concave cross section extending to the lower end of the main body 22 on both sides of a rectangular through hole 24 provided in the center longitudinal direction of the main body 22. The slider 2 is provided on the surface facing the back plate 13, and the ridge 2 of the slider 2 is provided.
0 and the long groove 30 of the operation piece 3 are formed so as to be fitted.
