To provide a slewing gear which can quickly perform a work from a locked state.SOLUTION: A rotary lever has a slot which is engaged with a first sub gear, and an operation pin which is connected to a lock member. The first sub gear has: a first toothed part which is engaged with a first main gear; a first non-tooth part which is released from engagement with the first main gear; a protrusive part with which the lock member is engaged; and a guide part which is engaged with the slot of the rotary lever. The rotary lever is moved in a first moving range in which the rotary lever is moved in the state that the slot and the guide part are not engaged with each other and a second moving range in which the rotary lever is moved in the state that the slot and the guide part are engaged with each other. The rotary lever performs release movement of the lock member for releasing a lock state of the lock member and the first sub gear when moving in the first moving range up to the second moving range, and rotates the first sub gear relatively to a substrate when moving in the second moving range, and performs transition from an engagement state that the first sub gear and the first main gear are engaged with each other to a release state that the first non-tooth part of the first sub gear faces the first main gear.SELECTED DRAWING: Figure 1

    【課題】ロックされた状態から早急に作業ができる回転装置を提供することを課題とする。【解決手段】回転レバーは、第一副ギヤと係合する長穴と、ロック部材と接続する操作ピンとを有し、第一副ギヤは、第一主ギヤと噛合する第一有歯部と、第一主ギヤとの噛合が解除される第一無歯部と、ロック部材が係合する突状部と、回転レバーの長穴と係合するガイド部とを有し、回転レバーは、長穴とガイド部とが非係合状態で移動する第一移動範囲と、長穴とガイド部とが係合状態で移動する第二移動範囲とで移動し、第二移動範囲に至るまでの第一移動範囲での移動にて、回転レバーは、ロック部材を、ロック部材と第一副ギヤのロック状態を解除するための解除移動をさせ、第二移動範囲での移動にて、第一副ギヤを基体に対して相対回転させ、第一副ギヤと第一主ギヤとが噛合している噛合状態から、第一副ギヤの第一無歯部が第一主ギヤに面する解除状態へと遷移させる。【選択図】図1
