Abstract
For the purpose of providing a thin pump designed to decrease the number of parts, the pump is provided with a rectangular parallelepiped cylinder (3) and a piston located inside of the cylinder, wherein the piston (4) reciprocates and oscillates in the cylinder (3) to vary capacity of the pump chamber (12) and to make the intake port (5) and the outlet port (6) open alternately, so that fluid is sucked from the intake port (5) into the pump chamber (12), compressed and discharged from the outlet port (6).
