Claims

[Scope of utility model registration request]

A steel combination oil made of a thin copper strip formed into an M-shaped cross section, and a ring member wound in a circle with the troughs of the 4-shape facing the inner circumference, and a coil spring arranged inside so as to press the ring member toward the outer circumference. In the ring, half iR1 of the root 12 of the trough is configured to be thicker than the radius R2 of the coil spring 3, and the coil spring 3 is closely inscribed in the root 12 of the ring member 1. A steel combination oil ring characterized in that oil windows 2 are provided evenly in the circumferential direction on two inclined surfaces 13 and 13 forming a valley.
