PROBLEM TO BE SOLVED: To provide a manual chain block, without a problem in strength itself together with miniaturization, by arranging a position of a reduction gear of a deceleration mechanism part nearer to the center, regardless of a bearing of a load sheave.SOLUTION: The load sheave 12 is turnably supported in first and second main frames 11a and 11b by bearings 13a and 13b via shaft parts 12a and 12b. A drawing process part 31 and an auxiliary plate 30 forming a bearing hole 33 of a shaft part 16br of a first reduction gear 16b, are arranged in the thrust direction around the bearing 13a for supporting the shaft part 12a in the load sheave 12 of the first main frame 11a so as to be attached to the first main frame 11a. |
