Claims

[Scope of utility model registration request]

An arm is attached to a central shaft arranged approximately horizontally so as to rotate in a vertical plane, a ratchet gear is fixed to the central shaft, and the arm is engaged with the ratchet gear to prevent the arm from rotating in one direction. A ratchet pawl is attached to the arm so as to rotate in both forward and reverse directions due to its own weight, and a raising pawl is provided that presses the ratchet pawl in a direction to remove it from the ratchet gear as the arm is rotated by a predetermined angle or more. Further, a support pin that supports the back side of the ratchet pawl that has been removed from the ratchet gear by the raising pawl is attached directly to the arm, and when the ratchet pawl is removed from the ratchet gear, rotation of the arm is prevented by the ratchet pawl and the ratchet gear. A rotation angle adjustment mechanism characterized in that the ratchet pawl is rotated by its own weight toward the ratchet gear by rotating the ratchet pawl in the direction of the ratchet gear.
