Title:
POWER TRANSMISSION DEVICE
Document Type and Number:
WIPO Patent Application WO/2015/146573
Kind Code:
A1
Abstract:
In a transaxle case (240), a scatter space (250) is configured by forming a projecting surface (252), which projects outwards of the vertical line (tangent line) extending upwards from a 90-degree rotation site (251) rotated 90 degrees from the vertical bottom of a differential ring gear (45), and an extending rib (260), which extends from the projecting surface (252) towards the rotation center of the differential ring gear (45) up to near the outer periphery of the differential ring gear (45). Further, the bottom surface of the extending rib (260) is formed as an inclined surface such that when the hydraulic fluid scattering into the scatter space (250) collides therewith, the hydraulic fluid is forced out towards a converter housing. Thus, the hydraulic fluid is made to scatter into the scatter space (250), to collide with the bottom surface of the projecting rib (260), and to be forced out towards the converter housing.
