Patent ID: 8715382

Claim:
A ventilation member, comprising: a tubular part, in an interior of which a gas passage for an object that needs ventilation is formed, the tubular part having a connection-end opening which is an opening on a side on which the object is to be connected, and a filter-end opening, and a body portion positioned between the connection-end opening and the filter-end opening; a gas permeable filter disposed at the filter-end opening of the tubular part to close the filter end opening; and a cover part, inside of which the tubular part is fit, wherein: the cover part includes a bottom portion that faces the gas permeable filter in an attached state where the tubular part is fit inside from a side of the gas permeable filter and a side wall portion that extends from the bottom portion so as to surround the filter-end opening and the body portion from outside; gaps functioning as gas passages that communicate with an exterior are formed in the attached state between the bottom portion of the cover part and the gas permeable filter and between the side wall portion of the cover part and the body portion of the tubular part; a material of the cover part is thermoplastic resin having no rubber elasticity; a material of the tubular part is elastomer; the cover part comprises fixing pieces formed on an inner surface of the side wall portion for securing the tubular part to the cover part, the fixing pieces each extending in a direction toward an opening of the cover part; the fixing pieces push the tubular part toward a center axis line of the tubular part in the attached state, so that the tubular part is allowed to undergo elastic deformation, the center axis line being parallel to a thickness direction of the gas permeable filter, and the fixing pieces are configured to contact a side portion of a side wall of the tubular part in the attached state.
