PROBLEM TO BE SOLVED: To provide a vehicular power transmission device which has an oil supply structure for supplying a lubricant to a contact part increasing calorific value by contact between a rolling body and an outer peripheral member.SOLUTION: A one-way clutch of a vehicular power transmission device is equipped with an inner peripheral member disposed in the inside of an outer peripheral member (22) so as to coaxially rotate, and connected with an output shaft (12); a rolling body (25) rolling between the outer peripheral member (22) and the inner peripheral member (23); and storing members (33 and 36) for storing the rolling body (25). At a side surface (36) of the storing members (33 and 36), a lubrication hole (50) is provided in parallel with an axial direction of the output shaft (12). At a reference position (DP) where the rolling body (25) starts engagement between the outer peripheral member (22) and the inner peripheral member (23), a lubricant is supplied from the lubrication hole (50) into between the rolling body (25) and the outer peripheral member (22). |
