アーマチヤを挿入していた。この組付構造では、
ブラシにスプリング荷重がかかり、組付し難いこ
とと、治具が必要であるという欠点があつた。 Conventionally, small motors use coil springs as brush springs, and motor assembly involves inserting the brush spring into a holder, pressing the brush against the spring pressure, and holding it with a jig, etc.
An armature was inserted. In this assembly structure,
The drawbacks were that a spring load was applied to the brush, making it difficult to assemble, and that a jig was required.

ことを目的とする。 In order to solve the above-mentioned drawbacks, the present invention has a protrusion formed on both sides of the brush holder where the brush is inserted.
By engaging the protrusion of the U-shaped elastic member and fitting the back side of the elastic member into the recess of the holder, the objective is to provide the advantage of easy assembly and no need for a jig. do.

ルである。 The present invention will be described below with reference to embodiments shown in the drawings. The donut disc-shaped brush holder 1 has a rectangular brush storage part 1c, a protrusion 1a formed on both sides of its tip, and a recessed part 1b formed on its outer peripheral end, and has a U-shaped elastic member 2. When assembled in the direction of the arrow in FIG. 3, the projections 2a formed on both sides of the tip of the elastic member 2 and the projection 1a, and the holder recess 1b and the back surface 2b of the elastic member 2 fit together. In the brush holder assembled state, the brush 4 is assembled in the housing part 1c, and the brush spring 3 is located between the brush 4 and the U-shaped elastic member 2, and presses the brush 4 against the commutator 5. 4a is a brush pigtail.

としないで取付が可能となる。 Since the present invention aims to improve the ease of assembling the brushes of a small motor, the assembling method will be described next. Third
The figure shows the assembled condition. First, the brush 4 is inserted into the storage part 1c of the brush holder 1, and then the commutator 5 is inserted. Next, from the outside, brush spring 3
is inserted, and the U-shaped elastic member 2 is pushed in from the outside until the protrusion 1a and the protrusion 2a, the holder recess 1b and the back surface 2b of the elastic member 2 fit together. This structure allows installation without the need for a jig.
