Abstract

PURPOSE:To enable weight reduction and continuous production, by combining two plastically worked steel plate elements with each other to manufacture a rod comprising a big end which is slidably fitted on the eccentric portion of the rotary shaft of a compressor and a small end which slides on the connecting portion of a piston. CONSTITUTION:Steel plates are plastically worked to prepare two elements 11a, 11b. These elements are coupled to each other to manufacture a rod 11. It is more efficient to shape the plastically worked steel plate elements 11a, 11b by advanced cold forging than by conventional burring or drawing. The elements 11a, 11b, which constitute the rod 11, are provided with projections 11e which constitute a big end 11c and a small end 11d. Connecting rod portions 11b, which couple the big and the small ends to each other, are provided with recesses which are located within the width of the connecting rod portions and serve as oil holes 11g.
