Abstract

A motor driving device includes: a printed circuit board; a surface mounted component group of multiple surface mounted components surface-mounted on a printed surface of the printed circuit board; a heat-generating component group of multiple heat-generating components that generate an amount of heat equal to or larger than a predetermined amount, the heat-generating component group being provided on the printed surface side of the printed circuit board; a fan configured to blow air to the heat-generating component group to thereby cool the heat-generating components; and a cover configured to block flow of air blown by the fan so that the air blown by the fan will not flow to the surface mounted components.
