A pulley (16) and a large diameter gear (18) are axially supported integrally on a fixed plate (10), an input shaft (17) and a small diameter gear (19) are axially supported integrally above the pulley (16), and the gears (19, 18) mesh with one another. A guide roller (33) and a guide plate (31) are disposed spaced apart to the left of the input shaft (17) to form a rope inlet path (35), and a guide roller (34) and a guide plate (32) are disposed spaced apart to the right of the input shaft (17) to form a rope outlet path (36). A support shaft (41) with a hole (40) for hanging a carabiner is installed on the fixed plate (10) below the pulley (16), and a guard plate (42) which closes an opening portion (30) on the front surface of the fixed plate (10) is axially supported with freedom to pivot. Further, a cam (50) which is free to approach and move away from the pulley (16) is axially supported with freedom to pivot, and the cam (50) is urged in the direction approaching the pulley (16) by means of a tension coil spring (50A). The cam (50) can be moved away from the pulley (16) by means of an operating member (54).
