PROBLEM TO BE SOLVED: To provide a device for carrying the muck in a tunnel which is easily retractable, capable of smoothly moving a drilling machine and a shotconcrete machine, and inexpensive. SOLUTION: This carrying device comprises a loading machine 1, a mobile crusher 10 and an extension belt conveyor 20, a forward end part 23a of a belt 23 of the extension belt conveyor 20 is movable in the longitudinal direction with respect to a body part 23b, and the forward end part 23a is longitudinally moved by the mobile crusher 10. The forward end part 23a of the belt 23 is moved backward with respect to the body part 23b and can be easily retracted by moving the mobile crusher 10 from the carrying position to the retracting position. Since the mobile crusher 10 is continuous to the extension belt conveyor 20 on one side of a tunnel, a drilling machine or a shotconcrete machine can be moved smoothly and freely. The carrying device comprises the loading machine 1, the mobile crusher 10 and the extension belt conveyor 20 in an inexpensive manner.
