持するものである。 Embodiments of the present invention will be described below based on the drawings. In FIG. 2, 4 is the yoke of the motor. Reference numeral 1 denotes a brush holder stay made of an insulating material such as a phenol laminate, and is provided with a notch 5. Reference numeral 6 designates a circuit breaker holder made of integral resin molding, which is composed of a side wall 7, a storage case 8, support parts 9 and 10 protruding from the outer surface of the side wall 7, and a boss 11. The outer surface conforms to the shape formed by the inner circumferential surface 4' of the yoke 4 and the notch 5 of the brush holder stay 1, and the support portion 9
The interval between and 10 is approximately equal to the plate thickness of the brush holder stay 1. In the above component configuration,
The assembly is as follows. First, when the circuit breaker 3 is pressed and stored in the storage case 8 of the circuit breaker holder 6 in the direction of the arrow, the boss 11
As shown in FIG. 3A, is located outside the terminal surface 3' of the circuit breaker 3 to prevent the circuit breaker 3 from coming off. The housed circuit breaker 3 is located in the housing case 8 as shown in the sectional view shown in FIG. And the second
As shown in the figure, the circuit breaker holder 6
The cutout portion 5 of the brush holder stay 1 is engaged with the support portions 9 and 10 of the yoke 4, and the brush holder stay 1 is assembled into the inner circumferential surface 4' of the yoke 4.
It supports the circuit breaker holder 6 in a pinched state.
