WIPO Patent Application WO/2012/001925
Kind Code:
Provided is a cap cover such that the clogging of a vent section and the intrusion of dust into a tank can both be suppressed. Also provided is a tank equipped with said cap cover. Said cap cover is equipped with a peripheral wall covering section (16b) and an annular seal section (17), said peripheral wall covering section (16b) serving to cover, from the outside, a filler neck (12) and a peripheral wall (13b) of an oil filler cap (13), on the entire periphery of the filler neck (12) around the axis line thereof, in such a way as to extend over the outer peripheral surfaces of the filler neck (12) and the peripheral wall (13b), and said annular seal section (17) being provided in such a way as to protrude inwardly from the portion of the peripheral wall covering section (16b) that covers the filler neck (12). The seal section (17) comes into close contact with the outer peripheral surface of the filler neck (12), with the result that between the peripheral wall covering section (16b) and the filler neck (12), there is formed a second vent section (20) whereby the outside air introduced through an opening of the peripheral wall covering section (16b) is guided to a first vent section (14), while being made to whirl around the axis line of the filler neck (12), said opening being located in such a way as to face a tank body (23).
