PROBLEM TO BE SOLVED: To provide a hoist device that realizes simpler, smaller, lighter structure of the entire device, at the same time, is able to prevent or minimize unnecessary fall of an object, and is able to perform hoisting and lowering operations timely, continuously, speedily, and efficiently.SOLUTION: A hoist device 1 according to the present invention comprises: a drive force source 2; a rotor 4 around which a traction member for hoisting a target object is wound; and cam mechanisms 78 and 79. The cam mechanisms couple an input member 40 and an output member 50 such that they are integrally rotatable while allowed for partially relative rotation. Also, the cam mechanisms are engaged with a rotation regulating part 60 by axially projecting by relative rotation of the input member 40 in a first direction (a) with respect to the output member 50. Thereby, the members 40 and 50 are coupled to the rotation regulating part 60 so as to be integrally rotatable. Also, by axially separating them from the rotation regulating part 60 by relative rotation of the member 40 with respect to the member 50 in a second direction (b), the member 40 and the member 50 are separated from the rotation regulating part 60.SELECTED DRAWING: Figure 1
【課題】装置全体の構造の簡素化及び小型・軽量化を図りつつ、対象物の不要な落下を防止する或いは最小限に抑えることができるとともに、タイムリーに連続的且つ迅速に巻き上げ及び降ろし作業を効率的に行なえる巻き上げ装置を提供する。【解決手段】本発明の巻き上げ装置1は、駆動力源2と、巻き上げ対象物を牽引するための牽引部材が巻回される回転体4と、カム機構78,79とを備える。カム機構は、入力部材40と出力部材50とを部分的な相対回動を可能にしつつ一体回転可能に連結し、出力部材50に対する入力部材40の第1の方向aの相対回動によって軸方向に突出して回転規制部50と係合することにより部材40,50を回転規制部60に一体回転可能に結合させるとともに、部材50に対する部材40の第2の方向bの相対回動によって回転規制部60から軸方向に離間することにより部材40と部材50とを回転規制部60から切り離す。【選択図】 図1
