により揺動自在に連接されている。As shown in FIG. 1, a closed-type compression assembly machine used in a refrigeration cycle has an electric motor section 2 and a compressor section 3 in a hole/closed case 1.
is stored. The compressor section 3 consists of a crank IlI] 6 which is fixed to the upper end of a shaft 5 which is pivotally supported by a frame 4 and rotates eccentrically, a piston 8 which moves reciprocatingly within a cylinder 7, and the piston 8 and the crankshaft 6. It is composed of a connecting rod 9 that connects the. The connecting rod 9 and the piston 8 are connected by a joint 10, as shown in FIG. That is, a sphere 11 is provided at one end of the connecting rod 9, and a sphere seat 12 is provided on the piston 8 to place the sphere 11.
After fitting into the first ball J-kei 12, the ball seat 12 is caulked so as to be swingably connected.

As explained above, the lubricating oil supply passages 35 may be formed at multiple locations. [Nuzu 1 of the invention] As explained above, in this invention, after fitting the sphere into the spherical seat of the piston, Before tightening the seat, wrinkles are formed in a part of the spherical seat and provided in the na slide supply dish path, so that when the spherical seat and the sphere are connected, a lubricant γ...supply path m is formed at the same time. By doing so, the manufacturing process can be improved and the total production cost can be reduced. In addition, because the spherical tf4J has a mountain road formed in the spherical tf4J, the disease drop γ11 is easily drawn in, and the effect that the durability is the same is -C.
