Abstract
A lubrication system for a transmission includes a first tubular portion, a second tubular portion, and a hollow cylindrical member. The first tubular portion has a cavity and includes a flange at one end adjacent to a gear shaft of the transmission. The first tubular portion has a first enlarged-diameter part extending in an axial direction from a joint at which the first tubular portion is joined to the second tubular portion. The second tubular portion has a second enlarged-diameter part that extends in the axial direction from the joint and has a diameter substantially equal to a diameter of the first enlarged-diameter part. The hollow cylindrical member is disposed in the first and second tubular portions and tightly fitted in the first and second enlarged-diameter parts of the first and second tubular portions joined to each other.
