In the elevating device (111), a first mast (13a) and a second mast (13b) extend in the vertical direction. A lifting table (15) ascends and descends along the first mast (13a) and the second mast (13b). Hoisting belts (39) comprise a first end (39a) fixed to the upper part of the lifting table (15) and a second end (39b) fixed to the lower part of the lifting table (15). Upper pulleys (117) support the hoisting belts (39). Drive pulleys (119) cause the hoisting belts (39) to move freely forward and backward. Idler pulleys (121) are disposed in front, in back or both in front and back of the drive pulleys (119). Lower pulleys (123) are disposed below the upper pulleys (117) and support the hoisting belts (39). Support members (127) are capable of swinging freely and of being fixed centered on a fulcrum (S), which is separated from the center of rotation (R) of the lower pulley (123) in the horizontal direction, and have a first end (127a) that extends in the horizontal direction from the fulcrum and is for supporting the lower pulley (123) so as to rotate freely.
