A power converter apparatus includes a case, a power converter which is in the case and converts input power to predetermined power and output the predetermined power, a first switch positioned in the case and connected to the converter component, a second switch positioned in the case and connected to the converter component, the second switch having a moving component which moves between first and second positions, and a cover which is installed on the case such that the cover covers the first switch and which moves in two mutually different directions relative to the case such that the cover is removed from the case. The cover has a contact portion which makes contact with the moving component of the second switch in the first position and which restricts movement of the cover in one or more of the two directions when the cover is moved in the two directions.
