POWER TRANSMISSION MECHANISM

摘要

PROBLEM TO BE SOLVED: To provide a power transmission mechanism capable of reducing rotational resistance.

SOLUTION: The power transmission mechanism comprises a clutch drum 140; force-feed oil passages 121 and a center oil passage 122 for feeding oil to the clutch drum 140; an oil reservoir part 160 provided below the clutch drum 140; an outer peripheral surface surrounding member 110 surrounding the outer peripheral surface 143 of the clutch drum 140 while facing the outer peripheral surface 143 with a clearance to the extent of not contacting the outer peripheral surface 143 when the outer peripheral surface 143 is rotated; and a trans-axle rear cover 100 provided continuously with the outer peripheral surface surrounding member 110 to surround an one-end face in the axial direction of the clutch drum 140. The axially opposite side to the trans-axle rear cover 100 in the outer peripheral surface surrounding member 110 is made an open end 111.
