The fitting piece 307B has a symmetrical shape with the fitting piece 307A.

  The insertion holes 308B and 309B are a pair of long holes through which the body belt 301 is inserted. The insertion holes 308B and 309B are formed adjacent to each other along the direction in which the body belt 301 is inserted. Furthermore, as shown in FIG. 5B, the insertion holes 308B and 309B are formed so as to be symmetrically inclined in the direction facing the body belt 301 so that the body belt 301 can be easily inserted.

  Since the waist belt 301 and the auxiliary belt 302 overlap each other, there is a possibility of interference with the auxiliary belt 302 when the buckle 217B is connected to the connecting fitting 304B. Therefore, the metal fitting body 306B has a curved shape in which the surface facing the body belt 301 is recessed so that the buckle 217B does not interfere with the auxiliary belt 302, and is inserted from the end opposite to the insertion piece 307B. As it approaches the piece 307B, the fitting piece 307B has an inclined surface 310B that has a shape that is inclined in a direction away from the body belt 301.

  When an annular fitting (not shown) similar to the annular fitting 303C is provided at a position between the left waist and the rear waist of the worker when the worker wears the auxiliary belt 302, the fitting piece 307B has a buckle. In order to prevent 217B from interfering with the annular metal fitting, it is formed to extend from the metal fitting body 306B to a position separated by a predetermined distance X from the annular metal fitting in a direction perpendicular to the longitudinal direction of the body belt 301.
