As shown in Japanese Patent No. 31645, it is fixed to the case with an elastic body interposed therebetween. However, if the elastic body is simply interposed in this way, the elastic body will suffer permanent deformation when used for a long period of time or when subjected to vibrations under conditions of rapid atmospheric temperature changes such as in automobiles. This has the drawback of causing the motor to rattle, making abnormal noises and reducing performance.

することができるものである。 Therefore, this invention eliminates the conventional drawbacks caused by simply interposing an elastic body between the motor and the case as described above, and prevents the motor from rattling even under adverse conditions. Our goal is to provide a motor fixing device that can fix a motor for a long time without having to worry about it.The gist of this device is to provide a motor fixing device that has a flange on the edge of the opening and a protrusion on the inner bottom; and a case having a spring formed with one end left on the inner bottom portion and having a pressing portion protruding inward of the case, the protrusion of the elastic body being in contact with the end face of the rear bearing portion of the motor. The periphery of the motor is covered with the elastic body, and the outside of the elastic body is covered with a case so that the pressing part of the spring presses the bottom of the elastic body, and the elastic body and the flange of the case The motor is fixed by being screwed to the member to be fixed. Therefore, since the motor is fixed under the double elasticity of the elastic body and the spring of the case, even if the elastic body is permanently deformed, it will still be subject to the elasticity of the spring of the case, which will solve the above problem. It is something that can be achieved.

The front surface of the motor 2 is in contact with the outer surface of one end, the front bearing part 4 of the motor 2 is fitted into the insertion hole 3 formed in the fixed member 1, and the rotating shaft 5 of the motor 2 is in contact with the fixed member. 1 and is adapted to be connected to the gear reduction device. Further, as shown in FIG. 2, engagement protrusions 6, 6 are provided on the outer surface of one end of the fixed member 1 on both sides of the insertion hole 3, and as shown in FIG. On the front surface, engagement holes 7, 7 are formed on both sides of the front bearing part 4, corresponding to the engagement protrusions 6, 6, and the engagement protrusions 6, 6 and the engagement holes 7, 7 are formed. The motor 2 is positioned relative to the fixed member 1 by engagement. Incidentally, contrary to this embodiment, the engaging protrusions 6, 6 may be provided on the motor 2, and the engaging holes 7, 7 may be provided on the fixed member 1, respectively.

８との間に挾持された形になつている。 The elastic body 8 is a bottomed cylindrical body made of natural rubber, for example, and covers the circumference of the motor 2 except for the front side.
The outer circumferential surface of the motor 2 is in close contact with the inner circumferential surface of the elastic body 8, and the terminals 9 of the motor 2 are disposed between the bottom inner surface of the elastic body 8 and the rear surface of the motor 2. A space has been created. Further, a protrusion 10 is formed at the center of the inner surface of the bottom of the elastic body 8, and this protrusion 10 comes into contact with the end surface of the rear bearing portion 11 of the motor 2, so that the motor 2 is connected to the fixed member 1 and the elastic body 8. It is shaped like a sandwich between the two.

As shown in the figure, a spring 13 is provided.
This spring 13 is composed of a notch 14 formed on the periphery except for one end of the spring 13, one end of which is bent inside the case, the other end extends toward the center of the case, and the other end has a hemispherical shape. Pressing part 15
is formed to protrude inside the case.

いるものである。 Flange portions 16 and 17 are formed at the front ends of the elastic body 8 and the case 12, respectively, and through holes 18 and 1 are formed in the flange portions 16 and 17.
Screws 20, 20 are inserted into 9, and the screws 20, 2
0 is the screw hole 21, 21 formed in the fixed member 1
The elastic body 8 and the case 12 are screwed to the member 1 to be fixed. As a result, the pressing portion 15 of the spring 13 presses the bottom of the elastic body 8, and the motor 2 is fixed to the fixed member 1.

音の量が少なくなる。 Therefore, since the rear end of the motor 2 is pressed by the force of the spring 13 via the elastic body 8, the elastic body 8 may deteriorate and become permanently deformed due to, for example, changes in ambient temperature. Also, the motor 2 will not be rattled. Further, the sound generated from the motor 2 is first blocked by the elastic body 8 and then further blocked by the case 12, so that the amount of sound leaking to the outside is reduced.

モータが弾性体とケースとで２重に囲まれている
ので、通常時においても外部へ漏れる音の量を少
なくすることができるものである。 As mentioned above, according to this invention, the motor is fixed so that it receives double elasticity from the elastic body and the spring of the case, so even if the elastic body is permanently deformed, the motor will not wobble. Therefore, it is possible to prevent abnormal noise and deterioration of motor performance even under adverse atmospheric conditions for a long time. Also,
Since the motor is surrounded by an elastic body and a case, the amount of sound leaking to the outside can be reduced even in normal conditions.
