To provide a scraper for applying a large peeling force and also for storing and retrieving a peeling blade and preparing for its replacement with one hand.

The scraper 1 includes: a plate-shaped support frame body 4; a peeling blade 2 detachably mounted to the support frame body 4 while a blade edge 111 projects from a front edge of the support frame body 4; and a plate-shaped support frame auxiliary body 5 for sandwiching the peeling blade 2 by working with the support frame body 4 to form a peeling blade holder 3. The support frame auxiliary body 5 is slidably engaged with the support frame body 4 between an operation position P1 where the blade edge 11 of the peeling blade 2 projects from the front edge 53a, a peeling blade accommodation position P2 which is displaced in an A1 direction to project toward the front edge more than the operation position P1 and a portion including the front edge covers the blade edge 11 of the peeling blade 2, and a peeling blade replacement position P3 which retracts in the A1 direction more than the operation position P1 so that most part of the peeling blade 2 is exposed to allow the removal of the peeling blade 2.
