Abstract
Provided is a chain block with which a reduction in size can be achieved while inhibiting a reduction in strength. A chain clock is provided with: a load-sheave hollow shaft which is provided with a load sheave that rotates to feed a load chain, said load-sheave hollow shaft having a hollow core along the axial direction thereof; a drive shaft which is inserted into the hollow core, and which is provided with a flange portion protruding radially outward from one end side to a base side of a separate gear part; and a reduction gear member provided with first reduction gear part which meshes with the gear part. An accommodating recess is provided at the one end side of the hollow core, said accommodating recess having a bottom part which is where the flange part is positioned, and which is in contact with the flange part. An inclined portion, which gradually inclines further towards the gear part side as said inclined portion approaches a center side in the radial direction, is provided to the flange portion. A chamfered portion is provided to a side of the reduction gear member, said side being the side nearest the flange portion.
