Abstract:
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
