The invention provides a power conversion device for a vehicle, which can restrain a load from being applied to a connector unit arranged in a storage shell even under the condition that an object collides from the front of the vehicle due to collision of the vehicle and the like. A power control unit (30) is mounted in a forecabin (FRM) of a vehicle (V), and is provided with a DC/DC converter (303), a housing case, and a low-voltage connector unit provided in the housing case. A first protruding portion and a second protruding portion are provided in a front-side region of the housing case. The low-voltage connector unit is provided so as to be located rearward of a first imaginary line (VL1) when viewed from the vertical direction, and at least a portion of the low-voltage connector unit is located between a first tangent point (P1), which is a common tangent line between the first protruding portion and the second protruding portion, and a second tangent point (P2), which is a tangent point between the first imaginary line and the first protruding portion, in the left-right direction. The second tangency point is a tangency point of the first imaginary line and the second protruding portion.

    本发明提供一种车辆用电力转换装置,其即使在由于车辆发生碰撞等而物体从车辆前方碰撞的情况下,也能够抑制向设置于收纳壳体的连接器单元施加载荷。动力控制单元(30)装载于车辆(V)的前舱(FRM)内,其具备DC/DC转换器(303)、收纳壳体、以及设置于收纳壳体的低压连接器单元。在收纳壳体的前侧区域设置有第一突出部和第二突出部。低压连接器单元设置为在从上下方向观察时处于比第一假想线(VL1)靠后方的位置、且至少一部分在左右方向上位于第一切点(P1)与第二切点(P2)之间,第一假想线是第一突出部和第二突出部的共用切线,第一切点是第一假想线与第一突出部的切点,第二切点是第一假想线与第二突出部的切点。
