A vacuum booster check valve comprises: a main body attached to a vacuum inlet; a first passage, an accommodation section, and a second passage; a valve seat formed in the first passage; a valve body accommodated within the accommodation section; and springs that bias the valve body toward the valve seat. The check valve also comprises vibration absorption sections whereby, when the valve body is seated on the valve seat, one part of the valve body absorbs more vibrations imparted to the valve body compared to other parts of the valve body.
