Abstract
Official abstract text for this publication.
Provided is a chain block with which wheel cover strength can be improved while inhibiting an increase in cost, without the need for separate reinforcement members. A chain block is provided with a wheel cover which is attached to a frame member, and which covers a hand-chain wheel having a hand chain looped thereover. A plurality of fixation holes for having fixation members inserted therethrough during attachment to the frame member are provided in peripheral edge sections of end-surface sides of the wheel cover, said end-surface sides being disposed facing the frame member. Wrap-around portions are provided to wheel-cover side surfaces which intersect the end surfaces, said wrap-around portions being formed so as to surround, at an angle exceeding 90, the fixation holes in the peripheral direction of the fixation holes.
