Figures 3 and 4 both show one embodiment of this invention, with Figure 3 being a perspective view showing the rear bracket and the closing ring, and Figure 4 showing the closing ring being contracted and fixed to the rear bracket. FIG. In the drawings, 1 is a DC motor, 2 is a rear bracket, 3 is a yoke, 17 is a plurality of drainage holes, 18 is a closing ring, and 19 is a through hole. Note that the same reference numerals in the figures indicate the same or corresponding parts. Figure 1 Figure 2

Claims

[Scope of utility model registration request]

A starter drainage device characterized in that water intake holes other than the drainage hole at the lowest part of the peripheral surface of the bracket are closed.

(2) Utility model registration claim 1, characterized in that the closing ring is formed of a heat-shrinkable synthetic resin film.
Drainage system for the starter as described in Section 1.

(3) A feature is that after the closing ring is shrunk by blowing hot air or pouring hot water on it, a through hole is formed by cutting out the closing ring corresponding to the drainage hole at the lowest part of the circumferential surface of the rear bracket. A drain device for a starter according to claim 1 of the utility model registration claim.

(4) The starter drainage device according to claim 1, which is a utility model registration, characterized in that the inro fitting portion of the yoke and rear bracket is covered by a closing ring.
