Claims

[Scope of claims for utility model registration] (1) Bracket 4 from which the output shaft 6 of the motor protrudes
On the other hand, a leaf spring 20 having fixing mechanisms at multiple locations on the outer diameter part is screwed into a female thread provided on the leaf spring 20, and the tip thereof comes into contact with the bracket 4 by the elasticity of the leaf spring 20. A stator 16 which includes a clearance adjustment bolt 32 and a coil 18 and is fixed to the side surface of the leaf spring 20 opposite to the side facing the bracket 4, and which can be fixed to the output shaft 6 protruding from the bracket 4. An armature 1 having a hub 10a and fixed to the output shaft 6 so as to face the stator 16 with a predetermined gap therebetween.
0, and the leaf spring 20 is attached to the clearance adjustment bolt 32.
A brake device for a motor, comprising an elastic body that applies a resilient force in the axial direction. (2) For the bracket 44 from which the output shaft 46 of the motor protrudes, there is provided a mounting plate 60 having fixing mechanisms at multiple locations on the outer diameter, and a female thread provided on the mounting plate 60 is screwed into the bracket 44 so that the tip thereof is connected to the mounting plate 60. a gap adjustment bolt 72 that contacts the bracket 44 due to the elasticity of the plate 60; a stator 56 that has a built-in coil 58 and is fixed to the side surface of the mounting plate 60 opposite to the side that faces the bracket 44; Said bracket 4
A hub 50 that can be fixed to the output shaft 46 protruding from 4
and an armature 53 connected to the flange portion 50a of the hub 50 via a leaf spring 51 so as to face the stator 56 with a predetermined gap therebetween.
and an elastic body that applies elastic force to the gap adjustment bolt 72 in the axial direction with respect to the mounting plate 60.
