スクレーパ。[Scope of Utility Model Registration Claim] In a scraper that is inserted between the outer peripheral surface of a rod that is fitted into a groove of a member to be attached and that performs reciprocating motion with respect to the member to be attached, a main dust strip that extends in the inner diameter direction and resiliently slides into contact with the outer peripheral surface of the rod; and a main dust strip that extends outward and in the inner diameter direction and is disposed on the outer diameter side of the main dust strip. The inner diameter of the outer circumferential surface is provided with a sub-dust lip that elastically contacts the outer inner surface of the groove, and the inner diameter of the outer circumferential surface is provided to provide a gap with the inner circumferential surface forming the bottom of the groove. is set smaller than the inner diameter of the inner circumferential surface of the groove.
