Provided is a hoisting machine which can reliably stop the rotation of a shaft-like member when a brake device has failed, and which can also improve the mounting strength of a pawl shaft. This hoisting machine 10 comprises a rotation lock device 100 which locks the rotation of a shaft-like member 25, the rotation lock device 100 including: a stopper support member 120 which rotates integrally with the shaft-like member 25; a stopper member 140 which is slidably supported by the stopper support member 120; and stopper locking means 110 each having a locking wall 114 which stops the rotation of the shaft-like member 25 by being contacted by the stopper member 140, wherein, when the shaft-like member 25 has accelerated the rotation toward a first rotation direction, the stopper member 140 protrudes to a position engaging with the stopper locking means 110 to stop the rotation of the shaft-like member 25, each stopper locking means 110 is integrated with a pawl shaft 115, and the stopper locking means 110 is mounted to a frame 12 via a stay bolt B1.
