とを特徴とする、リザーバタンク息抜き構造。 It consists of a reservoir tank body that has an opening at the upper end and a male threaded part on the outer periphery, and a lid that has a female threaded part on the inner periphery that can be screwed into the male threaded part, and the lower half of the female threaded part. A lower vertical groove for a breather is formed in the upper half of the male screw portion, and an upper groove for a breather is formed in the upper half of the male threaded portion, and when the lid is screwed onto the reservoir tank and the lid is closed and tightened, the upper groove is closed. A reservoir tank breather structure characterized in that the lengths of both vertical grooves are set such that the lower end level of the lower vertical groove is higher than the upper end level of the lower vertical groove.
