Claims

[Scope of utility model registration request]

In an apparatus in which an electric motor rotates an eccentric rotating body, the rotation of the eccentric rotating body causes a connecting rod to reciprocate, and the connecting rod operates an elastic movement member to transfer air. A bearing is provided, and the connecting rod is provided with a frame in which the rolling bearing is rotatably assembled, and the frame has a pair of edges that are always in contact with opposing portions of the outer circumference of the rolling bearing. An air pump that is provided only on the front and rear sides of the reciprocating movement of the connecting iron with respect to a rolling bearing, and converts the rotation of the eccentric rotating body only into a linear reciprocating movement along the front and rear direction of the reciprocating movement of the connecting iron.
