Abstract: A coolant drain mechanism of a casing for draining a coolant from an inside of a cooling channel is provided to a bottom of a casing housing a body to be cooled. A partitioning wall for partitioning the cooling channel into at least a pair of a first channel and a second channel, a drain port opened to both of the first channel and the second channel across the partitioning wall, and a drain stopper attachable to the drain port to seal the drain port are provided to the bottom. A portion of the drain stopper exposed into the cooling channel restrains a flow between the channels at a position where the drain port is in communication with the first channel and the second channel.
