To provide an elevating device with a frame can be simply attached to a guide rail.

A sheave block 42 by which a suspended sheave 20 is rotatably supported is removably coupled to a coupling link member 36 rotatably supported to a frame 10, by a fulcrum pin so as to be rotatable about the fulcrum pin. Further, an upper guide gib 14 is rotatably supported to the frame 10, and a coupling link member 36 is coupled to the upper guide gib 14 by means of an extendable link member 58 whose length can be adjusted by rotating a thread shaft 64 on which clockwise and counterclockwise threads are formed.
