載に於ける車室内環境に問題がある。10 is the s-Using (for fixing the stone) 0 In this way, in the conventional structure, in the mounting relationship between the shaft and the bearing, rotation is caused by tightening due to the difference in thermal expansion coefficients of the shaft, bearing, and support base depending on the temperature environment. To prevent this, a gap is provided in the thrust and radial directions between the shaft and the bearing, but due to the rotation axis fluctuating due to this gap, and due to shaft wear during long-term operation, the gap widens further. The noise is louder than the connecting part, which poses a problem for the environment inside the vehicle.

Covered by a case 11 provided with an opening for discharging to B',
It consists of a rotating part that is operated by the magnetic force between a coil 15 controlled by an electric circuit and a magnet 13 attached to the rotating part.

用ハウジングである。As a detailed view of the bearings 16A and 16B is shown in FIG. 4, the jewel 18 of the rotating shaft 14 has a conical V-cut shape. Further, the aforementioned jewel 18 is fixed to one of the bearings with a housing 19, and is further supported by a coil spring 2o. 21 and 22 are housings for fixing the jewel 19 and the coil spring 20.

以上のように本実施例は回転体の軸受１６Ａ。As described above, this embodiment uses the bearing 16A of the rotating body.

方向の支持を一つの受石１８により同時に実現できる。16B, the center of the jewel 18 is formed into a conical V-cut shape, and the tip of the rotating shaft 14 is received at the V-cut center, thereby providing unified support in the thrust and radial directions. This can be achieved simultaneously using two jewels 18.

ルダンパーとして振動伝達からくる騒音を抑制する。Since the spring pressure of the coil spring 2o configured in one of the bearings 1eB always acts in the thrust direction in the direction of the rotating shaft, the gap due to the clearance in the thrust and radial directions is eliminated, and the fluctuation of the rotating shaft 14 during rotation is suppressed. It is possible to reduce the noise to a very low level. In addition, lubricating oil is injected into the V-cut portions of the bearings 16A and 1 eB to smooth the movement of the rotating shaft and suppress friction noise. suppress.
