付板の歪みを解決するものではない。Also, "Microfilm of Japanese Utility Model Application No. 56-1764 (No. 57-115551)" discloses that a stepping (pulse) motor is fixed to a frame with an elastic body such as rubber by a screw or the like. There is. However, in this conventional example, since the vibration from the motor is transmitted through the screw and the elastic body is pressed and used, it is not possible to fully utilize the vibration and noise absorption function of the elastic body. It was not possible to obtain the desired characteristics in a motor with high vibration noise. Further, naturally, it does not solve the distortion of the mounting plate.

るという問題点もあった。Problems to be Solved by the Invention In the above-mentioned conventional configuration, when the mounting plate 2 and the stepping motor main body 1 are spot-welded, projection processing is performed in advance at the welding location. The plane of the mounting plate 2 may be distorted during welding, in which case the motor could not be properly mounted on the equipment. Further, since the stepping motor is essentially a motor having a high level of vibration and noise, there is a problem that vibration and noise are directly transmitted to the device through the mounting plate 2 which is rigidly connected.

いようにする。Action Since the mounting plate and the stepping motor body are integrally bonded via the elastic body of rubber, the elasticity of the rubber absorbs unnecessary strains and maintains the flatness of the mounting plate, and When the device is fixed to the chassis, the vibration and noise of the motor should be absorbed by the elasticity of the rubber so that it will not be transmitted.
実 施 例 以下図面を参照しながら本発明の一実施例について説

付板、３はゴムの弾性体である。FIG. 1 is a half sectional view of a stepping motor of the present invention. In the figure, 1 is a stepping motor body, 2 is a mounting plate, and 3 is a rubber elastic body.
ステッピングモータ本体１と取付板２とは環状のゴム

性体３は弾性を発揮するように適当な厚みを有して環状
に形成されている。The stepping motor body 1 and the mounting plate 2 are integrally bonded and fixed via an elastic body 3 made of an annular rubber. The rubber elastic body 3 is formed in an annular shape having an appropriate thickness so as to exert elasticity.

する。Next, as an example of the manufacturing method of the above-mentioned structure, the stepping motor main body or its outer frame 1 and the mounting plate 2 are arranged in the mold with high accuracy of related dimensions such as squareness and concentricity. The rubber mixed with the vulcanizing agent is injected into the space surrounded by the mold between and the vulcanized rubber is formed by appropriate heat and pressure.

ロジェクション加工が不要になり工数も低減している。When the vulcanized rubber is formed, an adhesive force is generated by vulcanization adhesion between the vulcanized rubber and the stepping motor main body, which is a metal plate, or its outer frame 1 and mounting plate 2, and the above-mentioned configuration of the present invention is obtained. In order to strengthen the adhesive strength, it is effective to use means such as roughening the surface of the metal plate, providing anti-slip projections, or metal plating. According to the above-mentioned manufacturing method, since an excessive strain force is not applied to the stepping motor main body, its outer frame 1 or the mounting plate 2, the dimensional accuracy can be maintained and both can be fixed integrally. The accuracy of the plane is also improved compared to the conventional one. In addition, the projection process is not required and the man-hour is reduced.
