Abstract
A bellows pump having a pump body including a suction path and a discharge path for a fluid and a bellows which is placed in a state where a basal end flange is airtightly fixed to the pump body to form a pump chamber with respect to the pump body. The bellows pump further comprises an actuation plate which is attached to a head portion of the bellows so as to cause the bellows to expand and contract with respect to the pump body. The bellows is further configured so that an airtight space is formed with between the actuation plate and a cup shape section formed in the head portion, such that a pressure rise can be absorbed and relaxed by contraction of the space portion caused by elastic film deformation of the thin head portion which faces the space portion.
