動が可能であるが、ここでは、その説明を省略する。A conventional door mirror device for an automobile basically has a case rotatably supported on a support of a vehicle side member, and this will be explained in more detail with reference to FIG. 5. The lower case 3 is rotatably attached to the support column 2 of the vehicle side member 1, and the mirror body 6 is attached to the support frame 5.
to be fixed. A motor 7 and a speed reduction mechanism 8 are disposed inside the upper case 4, and a final gear 9 of the speed reduction mechanism 8 is meshed with a drive gear 10 pivotally supported on the support column 2. The drive gear 10 is -
When a large external force is applied to the mirror body 6, the torque limiter 12 slips. Therefore, when power is applied to the motor 7, which allows the position of the mirror body 6 to be changed manually, the motor 7 rotates, the rotation of the input shaft of the motor is decelerated by the speed reduction mechanism 8, and the final gear 9 is rotated. The rotation of the final gear 9 attempts to rotate the drive gear 10 that meshes with it, but since the drive gear 10 is held in a fixed relationship with the column 2 by the torque limiter 12, the first drive gear The final gear 9, which does not rotate but rotates, revolves around the drive gear 10. As a result, the case 3.4, the frame 5, and the body 6 can be tilted in the right and up and down directions as a unit, but the explanation thereof will be omitted here.
ボール１３は車両側部材１とロアケース３との間に配さ

円滑な動きを確保するのに有効である。The ball 13 is disposed between the vehicle side member 1 and the lower case 3, and is effective in ensuring the positioning and smooth movement of the lower case 3 with respect to the vehicle side member l.

接近して物が配置できない不具合を生じる。Problems to be Solved by the Invention When the conventional example shown in this figure is rotated manually or electrically, the lower case 3 moves relative to the vehicle side member 1 via the moderation ball 13, and the ball 13 enters the next moderation hole, the lower case 3 moves up and down. That is, the ball moves from one moderation hole to the next moderation hole, and at that time, the mirror device moves up and down. Of course, this vertical movement is elastically absorbed by the spring 11 and does not cause the mirror device to wobble. However, a clearance in the height direction is required to allow this vertical movement, which causes a problem that objects cannot be placed close to the mirror device.

２によりトルクリミッタ−３３方向に付勢される。Example Refer to FIGS. 1-2. A support column 23 is vertically installed on a base 22 at the lower part of a vehicle side member 21. A lower case 24 and an upper case 25 are supported on this support 23, and a frame 26 including a mirror actuator unit 27 is integrally molded on the upper case 25. A mirror body 28 is fixed to the frame 26. A lower case 24 is supported on the lower side of the column 23, and an upper case 25 is supported on the upper side thereof. Inside the case 24.25, electric motor 29, internal teeth 30.50
It consists of a planetary gear having an external gear 31 and an eccentric gear 32, and is provided with a reduction mechanism called a 2KH-V planetary gear mechanism, a torque limiter 33, a final gear 34, a drive gear 35, and a spring 36. . The drive gear 35 is keyed to the lower part of the column 23. A cam plate 37 is keyed to the upper part of the column 23, and the first spring 36
This presses the ball 38 against the cam plate 37. 1st
The spring 36 is disposed within a hole provided in the upper case 25. Note that the final gear 34 is connected to the second spring 4
2, it is biased in the direction of the torque limiter 33.

２７に電流を流す。When the motor 29 is energized, the rotational movement of the motor 29 about the horizontal axis is converted into rotational movement about the vertical axis using the worm gear 40 or the like, and this rotational movement is transmitted to the eccentric gear 32. The rotation of the eccentric gear 32 having an eccentric shaft portion is fixed to the lower case 24, and is internally engaged with an internal gear 50 having n-1 teeth, for example, and an external gear having n-3 teeth. 31 is rotated around the internal gear 30 having the number of teeth of n, and the engagement points between the external gear 31 and the internal gear 30 are sequentially moved in the circumferential direction, and with one rotation of the eccentric gear 32, the internal gear 30 As a result, the internal gear 30 rotates by one tooth relative to the external gear 50 around the first shaft 39 in accordance with the rotational direction of the motor. The reduced rotation of the internal gear 30 is controlled by a torque limiter 33.
The signal is transmitted to the final gear 34 via. Since the drive gear 35 that meshes with the final gear 34 is keyed to the support column 23, the rotation of the final gear 34 causes the rotating gear 34 itself to revolve around the drive gear 35.
Since both ends of the shaft 39 are supported by the case 24.25, the case 24.25, frame 26, and body 28 rotate together around the support column 23. Note that 41 is an electric wire that allows current to flow through the motor 29 and the actuator unit 27.

、ミラー装置の上下動はない。When the mirror device rotates around the pillar 23, the spring 36
The ball 38 rotates around the support column 23 together with the upper case 25. When the ball 37 moves from one moderation hole of the cam plate 37 to the next moderation hole, only the ball 37 moves up and down, and this vertical movement is absorbed by the spring 36. Thus, there is no vertical movement of the mirror device.

であり、組付も容易である。Effects In the present invention, the final gear of the reduction mechanism and the drive gear of the column are arranged on the lower case side, so the axial support length between the upper case and the column is increased, and the backlash caused when the mirror device rotates is reduced. can be prevented. A part of the internal gear is provided in the upper case, and the external gear is meshed with the part of the internal gear. Since a part of the internal gear can be molded at the same time when the upper case is molded, it is inexpensive and easy to assemble.
