動翼のステイツク検知警報装置。 A pilot valve that is slidably inserted in the axial direction into a servo cylinder to which a variable blade operating lever is attached to change the direction of pressure oil, a pilot valve driver that drives the pilot valve, and a pilot valve that drives the pilot valve. A variable blade drive device comprising a link mechanism for transmitting the movement of a driving machine to the pilot valve, a bearing provided on the outer periphery of the pilot valve, and a link mechanism provided at an end of the servo cylinder that abuts the bearing. a stopper for regulating the amount of axial displacement of the pilot valve; and a relative displacement allowing joint inserted between the pilot valve driving machine and the link mechanism to elastically allow relative displacement in the axial direction between the two. and a switch mechanism attached to the relative displacement allowable joint and activated when the relative displacement exceeds a set value.
