PROBLEM TO BE SOLVED: To provide an accommodation case of a power transmission device for a vehicle which can suppress the exfoliation of a seal material caused by a flow of a lubricant.SOLUTION: In a transaxle case 10, a corner between a first mating face 16 and a first internal peripheral face 26 of a first casing member 12 and a corner between a second mating face 18 and a second internal peripheral face 30 of a second casing member 14 are chamfered, a first chamfered face 28 and a second chamfered face 32 which is larger than a chamfering width of the first chamfered face 28 are formed, and the second internal peripheral face 30 is protruded to the inside of the transaxle case 10 rather than the first internal peripheral face 26. Therefore, when a seal member 20 is protruded along the first chamfered face 28 and the second chamfered face 32, since the seal member stays in a groove 34 which is formed of the first chamfered face 28 and the second chamfered face 32, a protruded seal part 38 protruded from a clearance between the first mating face 16 and the second mating face 18 does not hinder a flow of a lubricant in the transaxle case 10.SELECTED DRAWING: Figure 2 |
