Title:
TRANSMISSION
Document Type and Number:
Japanese Patent JP2017180524
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To further improve the efficiency of a transmission including a first drum-like member and a second drum-like member coaxially disposed at the outer side of the first drum-like member.SOLUTION: A transmission includes: an intermediate shaft 27 serving as a shaft that discharges a hydraulic fluid from an oil hole 27b in conjunction with rotation; a clutch drum 80 having a first shaft part 81 coaxially disposed at the outer side of the intermediate shaft 27; and a clutch drum 90 having a second shaft part 91 coaxially disposed at the outer side of the first shaft part 81. A seal member 110 is disposed between the first shaft part 81 and the second shaft part 91, so that the hydraulic fluid flowing from the oil hole 27b of the intermediate shaft 27 to a lubrication object is prevented from entering into a space between the first shaft part 81 and the second shaft part 91. As a result, rotational resistance of the clutch drum is further reduced to improve the efficiency of the transmission.SELECTED DRAWING: Figure 4
