A connection member includes a nipple portion formed at one end and a first end face portion formed at an end part of the nipple portion. A valve cap includes a small-diameter portion; a large-diameter portion; a valve seat portion having a valve seal surface formed on an inner circumferential surface of the valve cap and located between the small-diameter portion and the large-diameter portion; and a fitting end portion fitted to the outer circumferential surface of the end part of the nipple portion. A valve body includes a bottom portion having an abutment part to abut the valve seal surface; a cylindrical open end portion extending from the bottom portion; a second end face portion formed at the open end portion in such a manner as to face the first end face portion; a first sliding portion provided on the open end portion; and a first flow path portion provided in the first sliding portion. The valve body is accommodated within the large-diameter portion in an axially slidable condition. A compression spring is disposed between the first end face portion and the second end face portion and adapted to bias the valve body toward the valve seat portion of the valve cap. One end portion of a flexible tube is fitted to the outer circumferential surface of the valve cap and the outer circumferential surface of the nipple portion.
