の安全装置。 A guide rail provided on the frame, a rack arranged parallel to the guide rail and fixed to the frame, a movable frame provided on the guide rail so as to be able to move forward and backward, and a rack provided on the movable frame that engages with the rack. In the rack-and-pinion drive mechanism, the pinion is rotatably supported on a support block, and the support block is rotatably supported on the movable frame. The pinion is mounted so as to be displaceable in the direction in which it lifts up from the rack, and the support block is biased by a spring having a predetermined elastic force, so that the support block is moved to a non-operating position where the pinion meshes with the rack at a normal position. A safety device for a rack-and-pinion drive mechanism, characterized in that a sensor is provided for holding the support block and detecting displacement of the support block from the non-operating position.
