PUMP WITH USE OF DIAPHRAGM

摘要

A diaphragm is provided in a pump case and defines a pump chamber. A swing body has a recessed part. A shaft member connects a rotary body to the swing body to deform the diaphragm so that the capacity of the pump chamber is changed, whereby the rotation of the rotary body can be converted into the swinging of the swing body. A mounting member projecting from the lower part of the diaphragm is fitted into the recessed part.
