PURPOSE: To easily perform mounting-demounting operation of a sheath and a tool or the like on a waist belt of an operator by installing one member of a mounting-demounting tool capable of mounting-demounting operation on the sheath or the like to house an edge part of a saw or the like, and installing the other member of the mounting-demounting tool on a suspending member having an installing part on the waist belt.

CONSTITUTION: A hanger main body 1 is composed of a sheath 2 to house an edge part of a saw or the like, a suspending member 8 having an installing part 7 to enable installation on a waist belt 6 to be wound round a waist of an operator and a mounting-demounting tool 5 to lock and release both 2 and 8. The mounting-demounting tool 5 is composed of one member 5a where two columns 9 and 9 having elastic inward hooking-fastening projections 10 on the upper ends are erected in both side parts and the other member 5b formed in a bag shape whose inside is formed as a cavity. When both members 5a and 5b are inserted, the hooking-fastening projections 10 on the columns 9 engage with projections formed in the other member 5b, and this engaging condition can be released by pushing operation of a pressing operation part 11.
