ル機構を構成している。 An embodiment of this invention will be described below with reference to the drawings. First, in FIG. 2, reference numeral 5 denotes a rear cover assembly, which includes a rear cover 6 manufactured by press working using a mild steel plate member, and a rear cover 6 which is welded to the upper and lower parts of this cover and manufactured by pressing the mild steel plate member. It is composed of stays 7 and 8. 9 is rear cover 6
10 is a screw insertion hole into which a brush holder is screwed. Reference numeral 11 denotes a cover part integrally connected to the lower stay 8, and is disposed so as to cover the outer circumferential surface of the drain hole 9, forming a labyrinth seal mechanism.

省略する。 Note that the rear cover assembly 5 shown in FIG.
Attach as shown in the figure. That is, 12 is a through bolt 13, 13 attached to the front machine frame of the starter (not shown).
At this time, the through bolts are passed through the holes 7a and 8a of the stays 7 and 8. 14 is a flat washer, 15 is a spring washer, 16 is a stator, 17 is a yoke, 18 is a pole, and 19 is an armature, and a rotating shaft 20 is rotatable by a ball bearing 21 attached to the rear cover 6. Supported. A brush holder 22 is screwed onto the rear cover 6, and a brush 23 is connected to a commutator 24 of the armature 19.
It slides into contact with the 25 is an armature core, and 26 is an armature coil. Note that since the operation of the DC motor 12 having such a configuration is well known, a description thereof will be omitted.
このようにすれば、水抜穴9がステー8と一体
に構成されたカバー11によつてラビリンスシー
