Patent number: 10995844Abstract: In a breather structure of a transmission, a gear chamber of the transmission is disposed between an engine and an electric motor control device for an electric motor, and a breather piping is inserted into a breather hole in an upper wall of the gear chamber. When viewed from above, in a vehicle width direction, a part of an intake system member and the electric power control device are overlapped together, and a part of the intake system member and the gear chamber are overlapped together. Therefore, a direction of water splashed up from a road surface and flowing forward is changed downward so that the breather hole is easily covered with water. However, since an atmosphere opening part of the breather piping is disposed above the electric motor chamber, even if the breather hole is covered with water, a breather function is not lost.Type: GrantFiled: June 29, 2020Date of Patent: May 4, 2021Assignee: HONDA MOTOR CO., LTD.Inventors: Hiroyuki Kita, Takafumi Maruyama, Katsuhisa Tanaka
