PROBLEM TO BE SOLVED: To provide a lower back supporter such as an auxiliary belt for obtaining a mounting state fitted to a lower back.SOLUTION: A band-shaped belt body 21 for obtaining the mounting state to enclose the outer circumference of the lower back by fastening a lower back belt 10 is stereoscopically formed so as to meet the outer circumference of the lower back with the use of a thermoplastic resin having cushion property. When forming it, a portion facing a sacrum includes a projection 25 in a shape simulating the sacrum. When the belt body 21 is mounted on the lower back, the projection 25 is strongly brought into elastic contact with the sacrum. The contact part receives the weight of a work tool supported by suspension so as to prevent the upper side part of the belt body 21 from inclining outward. Then, the mounting state fitted to the outer circumference of the lower back is obtained in the whole inner surface of the belt body 21. |
