1. A power conversion device, comprising:
a casing that has a front surface with an opening, and is configured to accommodate electrical components;
an insertion component including an insertion portion inserted from the front surface side into the opening; and
a gasket provided between the insertion portion and the opening,
wherein the casing has an inner wall surface being in contact with the gasket and a casing-side guide surface located on an inner side of the casing with respect to the inner wall surface in an insertion direction for the insertion portion,
wherein the casing-side guide surface is located on an inner periphery side of the opening with respect to the inner wall surface,
wherein the insertion portion has an outer peripheral surface being in contact with the gasket and at least one insertion component-side guide surface located on the inner side of the casing with respect to the outer peripheral surface in the insertion direction,
wherein the at least one insertion component-side guide surface is opposed to the casing-side guide surface,
wherein, when a distance in the insertion direction between the front surface and an end of the casing-side guide surface, which is closer to the front surface in the insertion direction, is represented by L1 and a distance between an inner surface of the gasket in the insertion direction and a distal end of the at least one insertion component-side guide surface in the insertion direction is represented by L2, the distance L2 is set larger than the distance L1.
