A hoist with built-in load sensitive automatic speed change device comprising: a speed-reducing mechanism configured to drive a load sheave axially supported by a frame (16, 17) on one side of the load sheave and a mechanical brake (6, 9) which applies a brake force by a load applied to the load sheave on the other side thereof; a drive shaft configured to couple the speed-reducing mechanism and the mechanical brake; a hand wheel that rotates the load sheave via the mechanical brake; a high-torque input member coupled to the hand wheel and configured to transmit a high load; a magnetic clutch coupled to the hand wheel via a speed-increasing mechanism and configured to transmit a low load by a magnetic force of a permanent magnet; and output transmitting means selectively coupled to either one of the high-torque input member or the magnetic clutch in accordance with the magnitude of the load and for transmitting a rotational operating force of the hand wheel to the mechanical brake, whereby the magnetic clutch is arranged between the speed-increasing mechanism and the hand wheel, the hand wheel and the speed-increasing mechanism are coupled by a hollow input member coupled to the hand wheel and provided so as to cover the outer periphery of the magnetic clutch so as to allow transmission of torque, characterised in that the hand wheel is axially supported by a drive member coupled to the output transmitting means of the mechanical brake and configured to be rotated thereby, and in that the output transmitting means is fitted onto a boss portion of the drive member so as to allow torque transmission to the boss portion. a speed-reducing mechanism configured to drive a load sheave axially supported by a frame (16, 17) on one side of the load sheave and a mechanical brake (6, 9) which applies a brake force by a load applied to the load sheave on the other side thereof; a drive shaft configured to couple the speed-reducing mechanism and the mechanical brake; a hand wheel that rotates the load sheave via the mechanical brake; a high-torque input member coupled to the hand wheel and configured to transmit a high load; a magnetic clutch coupled to the hand wheel via a speed-increasing mechanism and configured to transmit a low load by a magnetic force of a permanent magnet; and output transmitting means selectively coupled to either one of the high-torque input member or the magnetic clutch in accordance with the magnitude of the load and for transmitting a rotational operating force of the hand wheel to the mechanical brake, whereby the magnetic clutch is arranged between the speed-increasing mechanism and the hand wheel, the hand wheel and the speed-increasing mechanism are coupled by a hollow input member coupled to the hand wheel and provided so as to cover the outer periphery of the magnetic clutch so as to allow transmission of torque, characterised in that the hand wheel is axially supported by a drive member coupled to the output transmitting means of the mechanical brake and configured to be rotated thereby, and in that the output transmitting means is fitted onto a boss portion of the drive member so as to allow torque transmission to the boss portion.
