ことも常法の通りである。The power distribution rotor 14 rotates due to the integral rotation of the drive shaft 2, rotation shaft (A) 4, and rotation shaft (B) 7, and the power distribution device operates in a conventional manner. As the rotating shafts 41 and 7 rotate, the rotating plate 1o also repeats rotation across the projected light of the photoelectric pickup 18, and the light pulses passed through the light passing windows 22 and 23 are transferred to the photoelectric pickup. It is also common practice that a desired rotation angle detection signal is obtained by detecting with the light receiving section 18 and processing the obtained detection output with the electronic circuit device 19.

ようにされている。In the conventional power distribution device as described above, in order to maintain high detection accuracy by the rotation angle detection rotary plate 10, it is necessary to prevent the rotation axis 4.7 from shifting in the axial direction with respect to the photoelectric pickup 18 during rotation. You need to set it like this. Therefore, the positioning plate 11 is connected to the rotating plate 1o and the rotating shaft (A) 4.
and the flange portion (A) 6, and one of the pair of protrusions 12.12 provided on the positioning plate 11 is engaged with the engagement hole 13 provided on the flange portion (A) 6. , the other of the protrusions 12 is connected to the retaining hole 13.1 provided in the rotating plate lO and the flange portion (B) 9 of the rotating shaft (B) 7, respectively.
3, the rotating plate 10 and both rotating shafts 4.
Relative positioning between 7 and 7 is performed. If the positioning plate 11 and the rotary plate 10 are simply placed one on top of the other, and the flange portions 6.9t of both rotary shafts 4.7 are brought into contact with each other from both sides, and the screws 17 are tightened to make pressure contact, the contact surfaces will be It becomes extremely difficult to precisely adjust the relative positional relationship of the two as desired. Therefore, as mentioned above, the flange part (A) 4 has a peripheral table-like part 29 and a concave part 2 surrounded by the peripheral table-like part 29.
8, the depth of the recess 28 is larger than the thickness of the positioning plate 11, the positioning plate 11 is received in the recess 28, and the peripheral stand surrounds the recess 28. By pressing the shaped portions 29 one-on-one against the rotary plate 10, it is possible to precisely adjust the relative position between the contact surfaces of both elbows.

である。According to the experience of actually using the conventional power distribution device as described above, it has been found that there is a defect in that the accuracy of rotation angle detection by the photoelectric pickup 18 is easily reduced in an accident. The object of the present invention is to obtain a power distributor of this type free from such defects. As a result of various experimental studies for this purpose, the present inventors have found that the cause of the decrease in accuracy in rotation angle detection is not due to electrical factors in the photoelectric pickup 18 or the electronic circuit device 19, but is due to mechanical friction parts. It was confirmed that the abrasion powder was caused by adhesion to the light emitting surface and the light receiving surface of the photoelectric pickup 18. Further investigation revealed that the source of the abrasion powder was the positioning plate at the connecting portion of the rotating shafts 4 and 7. 1
1 and its contact surface, and that the abrasion powder generation mechanism was as follows. First, rotating plate 1
In order to precisely hold the o between the flanges 6.9 of the rotating parts 4 and 7, the height of the peripheral table-shaped part 29 of the flange part (A) 6 must be higher than the height of the positioning plate 11 in the recessed part 28. However, on the other hand, it is extremely difficult to precisely match the thickness of the positioning plate 11 with the depth of the recessed part 28 due to the force involved in actual work. It is housed in the recessed portion 28 in a floating and unstable state with a slight gap left in between. As a result, when axial vibration is applied to the drive shaft 2 during operation of the automobile, the positioning plate 11 moves axially within the concave portion 28 of the flange portion (A) 6, causing the rotating plate 10 and the concave portion to vibrate. Violent collision motion is repeated on the bottom surface of the portion 28, and abrasion powder is continuously generated. If this abrasion powder is scattered toward the inner wall of the Ujifugu 1 due to centrifugal force and adheres to the light emitting surface and light receiving surface of the photoelectric pickup 18, it will greatly reduce the detection accuracy of the desired rotation angle. This was a difficult point.

上記の事情を解明することかで１！だのである。The above circumstances may be considered as an extremely natural phenomenon at first glance when considering the structure of the power distribution device. A previously unexperienced problem of decreased rotation angle detection accuracy frequently occurs, and the cause has been investigated and the above circumstances have been clarified for the first time as a result of various follow-up tests. It is.

に防止できるようになった。FIG. 4 is a longitudinal sectional view of a main part showing an embodiment of the present invention, and FIG. 5 is a plan view and a longitudinal sectional side view of the elastic plate 30. As the elastic plate 30, a wave washer as shown in FIG. It is necessary to choose something that achieves the purpose of bringing it into pressure contact with 10. Due to the intervention of this plate 30, the positioning plate 11 is always held in pressure contact with the rotary plate 10, and the plate 30 itself is also held in pressure contact between the positioning plate 10 and the bottom surface of the recessed part 28 of the flange portion (A). As a result, the contact surfaces at the joint between the two rotating shafts 4.7 are held together stably and reliably, completely preventing the conventional accident of generating abrasion powder due to collision between the contact surfaces. It became so.

状バッキング材を利用してもよい。In the original state where the elastic plate body 30 is not subjected to any force when tightened by the screws 17 in the concave portion 28, the highest surface of the positioning plate 11 is pushed up higher than the height of the peripheral table-like portion 29;
When the above-mentioned tightening force reaches the final value, the positioning plate 1! The positioning plate 11 is stabilized by pressing down to the height of the entire peripheral table-like part 29, ensuring contact between the peripheral table-like part 29 and the rotary plate 10, and also ensuring contact sound between the positioning plate 11 and the rotary plate 10. to hold. As long as the plate body 30 has an elastic force that satisfies such conditions, the plate body 30 does not necessarily have to have a bent shape like a unibu washer, and a flat backing material may be used.
