To provide a rotary drive device having high reliability.SOLUTION: A rotary drive device includes a fixed portion, a moving portion, and a rotary body. The fixed portion has an oil passage. The moving portion is provided so as to be movable between a first relative position and a second relative position with respect to the fixed portion and to be reversibly movable between the first relative position with respect to the fixed portion and the second relative position with respect to the fixed portion, in accordance with a change in oil pressure in the oil passage. The rotary body is provided so as to be rotatable with respect to the fixed portion, and at the first relative position, conduction with the fixed portion is established via the moving portion, and at the second relative position, conduction with the moving portion is cut off.SELECTED DRAWING: Figure 2B

    【課題】高い信頼性を有する回転駆動装置を提供する。【解決手段】回転駆動装置は、固定部と、移動部と、回転体とを備える。固定部は油路を有する。移動部は、固定部に対し第1の相対位置と第2の相対位置との間を移動可能に設けられ、油路における油圧の変化に応じて、固定部に対する第1の相対位置と固定部に対する第2の相対位置との間を可逆的に移動可能に設けられている。回転体は、固定部に対し回転可能に設けられ、第1の相対位置において移動部を介して固定部と導通し、第2の相対位置において移動部との導通が遮断される。【選択図】図2B
