とするものである。[Detailed description of the invention] The present invention is an electric motor in which the output shaft is installed in a vertical direction and an umbrella-shaped drip-proof rubber is attached to the output shaft protruding from a bracket. It is an object of the present invention to provide an electric motor whose height is kept low and whose waterproofness is improved.

合する突出部６が設けられている。 Conventionally, in this type of electric motor, as shown in Fig. 1, an umbrella-shaped drip-proof rubber 3 is press-fitted and fixed to an output shaft 2 protruding from the center of a bracket 1, so that water transmitted from the end of the shaft is protected from the electric motor. Prevents intrusion inside. In addition, in Fig. 1, 4 is a waterproof cover that receives water from the drip-proof rubber 3, and the bracket 1 is
installed on. Further, as shown in FIG. 2, the drip-proof rubber 3 is provided with a protrusion 6 that fits into a ring-shaped groove (not shown) formed in the output shaft 2 in a shaft through hole 5 formed in the center. ing.

るという欠点があつた。 In the above configuration, it is necessary for the drip-proof rubber 3 to have a large contact area with the output shaft 2 in order to prevent the intrusion of water transmitted from the shaft end, and for this reason, the thrust direction dimension h 1 of the shaft through hole 5 is increased. There is a need to. Therefore, the height h 2 of the drip-proof rubber 3 in the thrust direction
It also gets bigger and uses more materials. As a result, the manufacturing mold becomes larger, resulting in a disadvantage that the manufacturing cost increases.
本考案は上記従来の欠点に鑑みてなされたもの

造に比べ小さくしている。 The present invention has been devised in view of the above-mentioned drawbacks of the conventional art, and one embodiment of the present invention will be described below with reference to FIGS. 3 and 4. Note that functional parts that are the same as those of the conventional components described above will be described using the same numbers. As shown in the figure, a tongue piece 7 that comes into pressure contact with the surface of the output shaft 2 is formed at the upper end of the drip-proof rubber shaft through hole 5.
The adhesion to the output shaft 2 is increased. As a result, the height h2 of the drip-proof rubber 3 in the thrust direction is smaller than that of the conventional structure.
以上の説明から明らかな如く本考案によれば、
防水性を損うことなく防滴ゴムのスラスト方向の
高さを抑えることができ、使用材料の低減を図る
ことができるという効果を奏する。 As is clear from the above explanation, according to the present invention,
The height of the drip-proof rubber in the thrust direction can be suppressed without impairing waterproofness, and the amount of materials used can be reduced.
