装置。 A ring-shaped spacer expander formed from a thin metal plate with an inward U-shaped cross section is placed in a ring groove carved on the outer periphery of the piston, and ring-shaped side rails are combined on both the upper and lower surfaces of the spacer expander. In the oil ring device, which is attached to the spacer expander and has a pressing protrusion formed on the inner peripheral edge of the spacer expander to press against the inner peripheral surfaces of both side rails, one end surface of the two end surfaces of the abutment part of the spacer expander. Alternatively, an oil ring device for a piston, characterized in that both end surfaces are formed in a chevron shape so that these end surfaces come into point contact at a portion between the outer circumferential surface and the inner circumferential surface of the spacer expander.
