Abstract
A coolant tank (15) has a bottom (16) and a tubular side wall (17) extending upright from an outer peripheral edge of the bottom (16). The side wall (17) has a plurality of outwardly protruding protrusions (18a, 18b, 18c, and 18d) formed thereon at predetermined intervals in the vertical direction. Providing the protrusions (18a, 18b, 18c, and 18d) increases the surface area of the side wall (17), whereby heat exchange with outside air is facilitated so that a coolant in the tank (15) is cooled down efficiently.
