However, since the connecting rod, bearing, and balance weight can be assembled in advance by press fitting, shrink fitting, etc., the connection is extremely strong, and there is no need to connect these joints while the air compressor is operating. It has the advantageous effects of no rattling, no wear on the connecting rod, etc., and stable operation of the connecting rod.

The main body casing has a motor chamber in which a motor is housed and a crank chamber in which a connecting rod is housed, and a head section having an intake valve and a discharge valve is provided at the upper end of the crank chamber. A diaphragm forming a compression chamber is interposed in the head portion between the crank chamber and the crank chamber, and the output shaft of the motor is connected to the connecting rod so that the connecting rod follows the rotation of the motor. Along with making it reciprocate,
In a diaphragm air compressor in which the head of the connecting rod is fixed to the diaphragm so that the diaphragm moves back and forth following the connecting rod, the upper end of the crank chamber is connected to the lower surface of the head of the connecting rod. The diaphragm type air compressor is provided at a position lower than the position of the crank chamber, and a slit is interposed between the upper end of the crank chamber and the diaphragm.
