Abstract
This invention provides a diaphragm pump that decreases the number of components or improves workability in assembling. A crank () to which the output shaft () of a motor () is pivotally attached has, in its upper surface, a ring-shaped insertion groove () with respect to the output shaft () as the center. A projecting driving shaft () is formed integrally with a driver (). When the lower end () of the driving shaft () is inserted into the insertion groove (), the axis () tilts. When the crank () rotates, an engaging portion provided in the insertion groove () engages with the lower end (). The driving shaft () rotates while changing the tilt direction of the axis () following the rotation of the crank (). Hence, when a diaphragm portion () attached to the drive element () of the driver () moves upward/downward, a pump chamber () expands/contracts so that a pump action is obtained.
