Claims

[Scope of utility model registration request]

A rack is fixedly mounted on a base on which a movable base is mounted in the moving direction of the movable base, and a pinion shaft that meshes with the rack is provided on the movable base, and the pinion shaft is provided with teeth, and the movable base is provided with a toothed portion. A ratchet that engages with the teeth is pivotally connected to a lever shaft that can only rotate about an axis that intersects with the axis of the pinion shaft, and a stopper is provided that restricts the lever shaft to rotate at a required angle. A forward/reverse feed device characterized in that the tooth portion is brought into engagement with different tooth grooves by rotating through a required angle.
