SLEWING DEVICE
PROBLEM TO BE SOLVED: To provide a slewing device whose structure can be inhibited from being large-scaled.SOLUTION: A slewing device comprises: a lifting mechanism comprising a lifting movable part that supports a rotation drive part; and a lifting drive part that supports the lifting movable part and lifts/lowers the lifting movable part. The lifting drive part comprises: a base; a first arm and a second arm that are supported on the base in a state in which the arms are rotatable while taking a rotation shaft as their fulcrum, and are connected to the lifting movable part in a state in which the arms are slidable; a driving source that is fixed on the base and rotates; and a power transmission device comprising a first transmission unit that connects with the driving source and the first arm, converts rotation of the driving source to linear motion to transmit the motion to the first arm, and rotates the first arm in linkage with the linear motion, and a second transmission unit that connects with the driving source and the second arm, converts the rotation of the driving source to linear motion to transmit the motion to the second arm, and rotates the second arm in linkage with the linear motion.SELECTED DRAWING: Figure 6
【課題】構造が大掛かりになることを抑制できる旋回装置を提供する。【解決手段】回転駆動部を支持する昇降可動部及び昇降可動部を支持し、昇降させる昇降駆動部を備える昇降機構を備える。昇降駆動部は、基体と、基体に回転軸を支点として回転可能な状態で支持され、かつ、昇降可動部に摺動可能な状態で連結されている第１アーム及び第２アームと、基体に固定された回転する駆動源と、駆動源及び第１アームと連結し、駆動源の回転を直線運動に変換して第１アームに伝達し、直線運動に連動させて第１アームを回動させる第１伝達ユニット及び、駆動源及び第２アームと連結し、駆動源の回転を直線運動に変換して第２アームに伝達し、直線運動に連動させて第２アームを回動させる第２伝達ユニットを備える動力伝達機構と、を備える。【選択図】図６
