に構成してなることを特徴とする位置検出装置。 Driven by a drive source fixed at a fixed position,
A ball screw mechanism converts the linear motion of a moving body that moves linearly in a direction toward and away from the drive source into a rotational motion of a rotary shaft of a rotary encoder, and the rotary encoder causes the aforementioned movement. A device for detecting the position of a body by detecting the amount of movement of the body from a reference position, wherein a nut of the ball screw mechanism is fixed to either one of the moving body or a drive source, and the nut is fixed to one of the other. A screw shaft screwed into the rotary encoder is provided rotatably and parallel to the moving direction of the moving body, and the rotary shaft of the rotary encoder is connected to one end of the screw shaft,
A position detection device characterized in that, when the movable body moves, the screw shaft and the encoder shaft are rotated by the nut and move relative to the nut.
