検出装置。 A position detection plate is connected to a blade angle operation rod that is inserted into the driven side hollow main shaft connected to the drive side main shaft with a coupling member and moves up and down to change the blade angle of the movable blade. In the blade angle detection device for a movable blade-shaped fluid machine, the blade angle detection device for a movable blade-shaped fluid machine detects the vertical position of the blade from the mutual spacing with a non-contact displacement meter installed opposite thereto, and detects the blade angle based on the detection position of the position detection plate. an operating rod or a gear that moves the operating rod up and down, and the position detection plate; and a reducing motion conversion mechanism that converts the vertical movement of the operating rod into a proportionally small amount of movement and transmits it to the connecting rod and the connecting rod. 1. A blade angle detection device for a movable blade-shaped fluid machine, characterized in that the blade angle detection device is connected by interposing the blades.
