<p>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 (10) is provided with a wheel cover (14) which is attached to a frame member (12), and which covers a hand-chain wheel (80) having a hand chain (C2) looped thereover. A plurality of fixation holes (147) for having fixation members (SB) inserted therethrough during attachment to the frame member (12) are provided in peripheral edge sections of end-surface (143) sides of the wheel cover (14), said end-surface sides being disposed facing the frame member (12). Wrap-around portions (148) are provided to wheel-cover (14) side surfaces (142) which intersect the end surfaces (143), said wrap-around portions being formed so as to surround, at an angle exceeding 90, the fixation holes (147) in the peripheral direction of the fixation holes (147).</p> |
