PROBLEM TO BE SOLVED: To easily attach and detach a conveyor belt. SOLUTION: One of a pair of support arms 9a, 9b having one end part supported by a stand 1 is detachably supported on the stand 1. A conveyor frame 21 arranged between a pair of support arms 9a, 9b is divided into a front frame 21a and a rear frame 21a to be rotatably connected. The front frame 21a is provided with a drive pulley 24 for driving of a conveyor belt 23 extended between belt guides 22a, 22b on both ends of the conveyor frame 21 and a tension roller 25 for tensile force, and a pulley shaft of the drive pulley 24 is rotatably supported by a bearing part 3a arranged on the stand 1. A lock screw inserted into the other end part of a pair of support arms 9a, 9b is screwed in the front frame 21a. Sagging is imparted to the conveyor belt 23 by folding-up of the rear frame 21b, the connection of one support arm 9b and the stand 1 is released, and the conveyor belt 23 is inserted and extracted from clearance formed between the stand 1 and the other side part of the conveyor frame 21.
