MANUFACTURING METHOD OF RECEIVERDRIER

摘要

PURPOSE: A manufacturing method of a receiver driver is provided to improve productivity by forming a retaining protrusion and an insertion groove by cutting the inner surface of the receiver driver. CONSTITUTION: A manufacturing method of a receiver driver is as follows. A receiver driver tank(20) is formed in a pipe shape. A rail(22) is formed in the inner surface of the receiver driver tank in a longitudinal direction. A hanging protrusion(24) is formed by cutting a part of the rail. An insertion groove(26) is formed in the bottom inner surface of the receiver driver tank. A filter(30) is inserted inside the receiver driver, and top end of the filter is fixed by the hanging protrusion. A lower cap(40) is inserted into inside the receiver driver tank, and fixes the filter. A snap ring(50) is inserted into the insertion groove, and fixes the lower cap.
