PROBLEM TO BE SOLVED: To provide a transaxle case in which peeling of seal agent caused by circulation of oil in the case is restricted and leakage of oil from within the case is prevented.SOLUTION: A transaxle case is a case including a first case member 40 and a second case member and capable of storing gears and oil therein. At least one of mating surfaces of the first case member 40 and the second case member includes a groove part 42 extending in a peripheral direction and a chamfer part 43 arranged at an inner end part 41a to be continuous with a groove 42 along its circumferential direction. At least a portion positioned along an outer circumference of a gear at the mating surfaces 41 having the groove 42 and the chamfer 43 includes a groove 42, a portion not positioned along the outer circumference of the gear includes the chamfer part 43 and a sectional shape of the groove 42 perpendicular to the extending direction of the groove 42 includes a region where a depth in parallel with a normal direction of the mating surfaces 41 becomes deep as it faces outside.SELECTED DRAWING: Figure 2 |
