Title: Power transmission apparatus for vehicle
Inventor: AIDA YUSUKE
IPC: B60K6/405
Filed: 2019-08-22
Abstract: To provide a structure suppressing generation of a breakage hole communicating the inside and the outside of a case of a power transmission apparatus for a vehicle, even upon a collision of the vehicle.SOLUTION: Even if a vehicle 10 comes into a collision and loads F2 are transmitted to a cover 25 via bolts 34 tightened into a mount fastening portion 36, the crack generated in the cover 25 can be caused to propagate along the direction in which bolt tightening holes 40 and holes 42 are arrayed. As a result, if the cover 25 is broken, it breaks along the crack, and therefore generation of a breakage hole communicating the inside and the outside of the cover 25 can be suppressed. With regard to this, it is unlikely that a motor 26 is exposed to the outside even if the cover 25 is broken. Thus, the decrease in the safety can be suppressed.SELECTED DRAWING: Figure 8
