摘要： PROBLEM TO BE SOLVED: To provide a vehicular power transmission device so constructed that the carrier of a planetary gear device is spline-fitted to a case to stop its rotation, for suitably suppressing the occurrence of rattling between the carrier and the case. SOLUTION: A disc spring 76 is provided for backlash compensation between the carrier CA2 and the case 30 in the thrusting direction. The backlash compensation between the carrier CA2 and the case 30 in the thrusting direction (the axial direction) prevents sounds when mutual members collide with each other in the thrusting direction. The carrier CA2 is pushed against the case 30 to produce friction force between the carrier CA2 and the case 30, thereby suppressing the occurrence of rattling with spline backlash formed between the carrier CA2 and the case 30 in the peripheral direction (the rotating direction) when the mutual members collide with each other.

摘要： PROBLEM TO BE SOLVED: To provide a seal structure using liquid gasket for minimizing the entry of oil into an interface due to an oil flow without establishing the sealing condition of an interface area between the liquid gasket and each member. SOLUTION: An oil shielding part is provided on the interface 36 upstream of the oil flow F1.
