ヘツド。 A hollow cylindrical spindle having a contact at its tip is slidably but non-rotatably mounted on a main body, and a drive shaft fitted into and screwed into the hollow part of the spindle is rotatably and axially axially attached to the main body. A motor is connected to the drive shaft, and a displacement detector is provided to detect the amount of movement of the spindle from the rotation amount of the drive shaft, and the spindle is supported between the spindle and the main body. The present invention is characterized in that a spring is provided that biases the drive shaft in one direction, and an elastic member is provided between the spindle and the fulcrum of the drive shaft to prevent the spindle and the drive shaft from coming into direct contact in the axial direction. micrometer head.
