摘要: 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).

摘要: Provided is a chain block with which a reduction in size can be achieved while inhibiting a reduction in strength. A chain block (10) is provided with: a load-sheave hollow shaft (20) which is provided with a load sheave (23) that rotates to feed a load chain (C1), said load-sheave hollow shaft having a hollow core (24) along the axial direction thereof; a drive shaft (70) which is inserted into the hollow core (24), and which is provided with a flange portion (71) protruding radially outward from one end side to a base side of a separate gear part (72); and a reduction gear member (60) provided with a first reduction gear part (61) which meshes with the gear part (72). An accommodating recess (27) is provided at the one end side of the hollow core (24), said accommodating recess having a bottom part (27a) which is where the flange part (71) is positioned, and which is in contact with the flange part (71). An inclined portion (73), which gradually inclines further towards the gear part (72) side as said inclined portion approaches a centre side in the radial direction, is provided to the flange portion (71). A chamfered portion (61a) is provided to a side of the reduction gear member (60), said side being the side nearest to the flange portion (71).
