構室の水抜き装置。 In the belt transmission mechanism chamber, which is formed by a case and a cover that are joined via a gasket, cooling air circulates inside, and a water drain is provided at the lowest mating surface, the case and cover at the bottom of the chamber are connected to each other. The wall thickness of the mating surfaces is set to match only near the water drain part, and in most cases, the case side is thicker than the cover side. It is set to be wider than the wall thickness of the mating surface on the case side so that it protrudes, and is cut at the same height as the upper edge at the position where the wall thickness of both mating surfaces near the drain part matches. A water draining device for a belt transmission mechanism chamber, characterized in that a cutout is formed.
