PROBLEM TO BE SOLVED: To provide a breather structure which contributes to downsizing of a vehicle motor driving device.SOLUTION: A breather structure of the invention includes a casing (25), which forms an outer shell of a vehicle motor driving device, and an outlet hole (43), which allows communication between a space (44) defined by the casing and an external space of the casing, in the vehicle motor driving device (10) including a motor for driving wheels. A flexible structure comprising a fiber material, a soft foam material, and a soft resin material is provided on an inner wall surface of the outlet hole.SELECTED DRAWING: Figure 3
