Abstract

PURPOSE:To easily form a groove so as to improve lubricating performance by press forming at least one groove continued over a rotary shaft from one end to the other end thereafter securing a crank member to this rotary shaft. CONSTITUTION:A crank 3 is eccentrically secured to the periphery of a rotary shaft 1 supported to a cylinder 6 in a casing 5 by bearings 7, 8, and a cylindrical roller 9 is mounted being fitted eccentrically to the periphery of the crank 3. By rotating the rotary shaft 1 by a motor 13, the roller 9 is eccentrically rotated, compressing fluid. In the case of a compressor thus obtained, when the rotary shaft 1 is molded, a core metal 14, providing a recessed groove 14a, is inserted into an internal diameter of a pipe material 2. This recessed groove 14a is formed into a spiral shape by a pitch corresponding to the pitch of a groove 4 molded in the pipe material 2. Next by press molding from the external diameter side, the groove 4 is molded over the pipe material 2 from one end to the other end, thereafter the crank 3 is secured to the pipe material 2.
