Title:
POWER TRANSMISSION DEVICE FOR VEHICLE
Document Type and Number:
Japanese Patent JP2017106550
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a structure capable of suppressing abrasion of a shaft member and an idling gear, in a structure in which the idling gear is fitted to the shaft member not via a needle bearing.SOLUTION: Since spline teeth 82 subjected to crowning in a circumferential direction of the input shaft 12 are formed on a region radially overlapping with a third input gear 32c, of an input shaft 12, a bearing pressure P between an inner peripheral face 84 of the third input gear 32c and the input shaft 12 is lowered, and abrasion and seizure between the third input gear 32c and the input shaft 12 can be suppressed. Further, since the inner peripheral face 84 of the third input gear 32c has a circular shape when viewed from an axial C direction, a gear rattling sound in sliding of the input shaft 12 and the third input gear 32c can be also suppressed.SELECTED DRAWING: Figure 3
