装置。[Scope of Claim for Utility Model Registration] A brake rod that constitutes a part of a brake device that transmits the braking force generated in a brake cylinder to a brake shoe, a threaded cylinder into which the brake rod is screwed, and a brake rod that is connected to a brake rod that is connected to the brake rod. a rotary drive unit that rotates in forward and reverse directions and whose rotational feed amount rotates in proportion to fluctuations in the brake shoe clearance; a drive clutch that is a one-way rotation mechanism that rotates in conjunction with the rotation drive unit; A brake shoe clearance automatic adjustment device having a driven clutch that transmits unidirectional rotation to the threaded cylinder when the rotation angle exceeds a certain angle, and a return spring that biases the active clutch toward the driven clutch,
The active clutch and the outer cylinder constituting a part of the rotary drive unit are coupled to each other by engagement of spiral grooves inclined at a constant angle with respect to the rotation axis, and An automatic brake shoe clearance adjustment device characterized in that a viewing angle θ is set as follows: θ>tan −1 μ (μ: friction coefficient of a joint portion).
