PURPOSE:To maintain excellent lubrication of a one way clutch by forming grooves for leading lubrication oil in the space between an outer race and a brake gear to a spline side toward the radial direction on the side face of the outer race. CONSTITUTION:Grroves 36 and 37 are formed toward the radial direction of an outer race 31 on the side face of the outer race 31 facing to the space 38 formed between the outer race 31 of a one way clutch 25 and a brake gear 24. Since lubrication oil flows smoothly due to the centrifugal force caused by the rotation of the outer race 31 to the side of a spline 41 through the grooves 36 and 37 in the space 38, the lubrication oil is prevented from the residence in the space 38, the lubrication of the one way clutch 25 is maintained excellently and also the working of the clutch 25 becomes smooth and reliable. |
