Inverter case
An inverter case is provided on a transaxle of a vehicle so as to be inclined downward toward a vehicle front side, and the inverter case includes: a refrigerant passage connection portion provided on a front side surface of the inverter case in a longitudinal direction of the vehicle, the refrigerant passage connection portion having a shaft seal structure; a refrigerant passage member disposed on the front side surface of the inverter case and connected to the refrigerant passage connection portion by the shaft seal structure; and a projecting portion provided on an upper part of the front side surface of the inverter case, the projecting portion being configured such that a front side end of the projecting portion is placed at the vehicle front side relative to a front side end of the refrigerant passage member in the longitudinal direction of the vehicle.
1. An inverter case provided on a transaxle of a vehicle so as to be inclined downward toward a front side of the vehicle, the inverter case comprising:
a refrigerant passage connection portion provided on a front side surface of the inverter case in a longitudinal direction of the vehicle, the refrigerant passage connection portion having a shaft seal structure;
a refrigerant passage member disposed on the front side surface of the inverter case wherein one end of the refrigerant passage member is connected to the refrigerant passage connection portion by the shaft seal structure, another end of the refrigerant passage member is connected with a face seal structure to an opening on the front side surface of the inverter case, and the refrigerant passage member is configured to introduce, into the inverter case, refrigerant flowing from outside the inverter case, wherein the face seal structure is formed of a flange portion; and
a projecting portion provided on an upper part of the front side surface of the inverter case, the projecting portion being configured such that a front side end of the projecting portion is placed at the front side of the vehicle relative to a front side end of the refrigerant passage member in the longitudinal direction of the vehicle.
2. The inverter case according to claim 1 , wherein:
an outside diameter of the refrigerant passage member connected to the refrigerant passage connection portion is smaller than an inside diameter of a refrigerant passage pipe provided inside the inverter case and the refrigerant passage pipe is connected to the refrigerant passage connection portion.
3. The inverter case according to claim 1 , wherein:
a position of the front side end of the projecting portion is generally aligned with a position of a front side end of the transaxle when viewed from a vertical direction.
4. The inverter case according to claim 1 , further comprising:
a cooling unit disposed in the inverter case and connected to the refrigerant passage connection portion with the shaft seal structure; and
a leaf spring biased toward the front side of the vehicle.
