Abstract
To provide a hand operated chain block capable of being downsized while enabling a hand chain to be easily wound over a hand wheel without disassembling the hand wheel from a chain block body when the hand chain is seated in the hand wheel, a hooking groove for the hand chain to be hooked is formed in an outer plate of the hand wheel having an inner plate and the outer plate between which the hand chain is fitted. For winding the hand chain over the hand wheel, it is only necessary that after the hand chain is hooked by the hooking groove, the hand wheel is turned.
