Disclosed is a manual chain block that achieves a more compact overall device and also does not lose the strength of the device itself by means of the position of a reduction gear of a speed reduction mechanism section being able to be positioned closer to the center regardless of the bearing of a load sheave. In the manual chain block, a load sheave (12) is supported rotatably by a first and second primary frame (11a, 11b) by means of bearings (13a, 13b) with axle sections (12a, 12b) therebetween. A supplemental plate (30)which forms, in the direction of thrust: a bearing hole (33) of an axle section (16br) of a first reduction gear (16b); and a drawn section (31)is, in a manner so as to supplement the aforementioned first primary frame (11a), disposed at the periphery of the bearing (13a) that supports the axle section (12a) of the load sheave (12) at the first primary frame (11a).
