PROBLEM TO BE SOLVED: To provide a locking device for a coupling member for mounting a cargo implement, which dispenses with machining by eliminating a guide groove for a coupling pin, and reduces clogging with sediment etc. SOLUTION: In this locking device for the coupling members 15 and 16 for coupling the backside of the cargo implement 2 with a coupler body 3 of a working machine 1, supporting members 17 and 18 for fitting and supporting the coupling members 15 and 16 are provided in right and left side parts of the coupler body 3; outside members 21 and 22 are provided outside the supporting members 17 and 18; inside members 23 and 24 are provided inside the supporting members 17 and 18; flange parts 15a and 16a are formed in almost central parts, in the axial direction, of the coupling members 15 and 16; stopper members 25 for regulating the inward movement of the coupling members 15 and 16 by abutting on the flange parts 15a and 16a are fixed to the inside members 23 and 24; the coupling members 15 and 16 are fitted into mounting holes 12 of the cargo implement 2 by making the flange parts 15a and 16a abut on the supporting members 17 and 18, so that a locked state can be brought about; and the flange parts 15a and 16a abut on the stopper members 25, so that an unlocked state can be brought about.
