| 摘要 |
The present invention provides a vehicle power transmission device which can maintain an aligning function without increasing the preload of a radial thrust bearing of a one-way clutch. The radial thrust bearing (34)possesses an inner ring (36) which rotates integrally with an output shaft (12), and forms an annular first rolling surface (S1) located at the radial inner side and an annular fourth rolling surface (S4) located at the radial outer side; an outer ring (35) rotating integrally with a swinging rod (22) and forming an annular second rolling surface (S2) located at the radial outer side and an annular third rolling surface (S3) located at the radial inner side of the fourth rolling surface (S4); a plurality of first rolling bodies (37i) configured between the first and second rolling surfaces (S1,S2), and a plurality of second rolling bodies (37o) configured between the third rolling surface (S3) and the fourth rolling surface (S4). |
