Abstract
Official abstract text for this publication.
A groove processing device, which processes a cylinder groove to an inner circumference of a cylinder to protrude from an inner circumferential surface toward an outer circumferential surface side and extend in a center line direction of the cylinder, includes: a first groove processing unit that process both end portions of the cylinder groove in a circumferential direction thereof, and a second groove processing unit that processes a center portion of the cylinder groove in the circumferential direction thereof, wherein an outermost circumferential portion of each of the first groove processing unit and the second groove processing unit being formed to be a chevron shape so that a center portion thereof in the circumferential direction of the cylinder protrudes, and an inclination angle from a vertex portion in the outermost circumferential portion of the first groove processing unit is larger than that of the second groove processing unit.
First claim
