PROBLEM TO BE SOLVED: To prevent a member such as an anchor main body 1 and a lining plate 10 or the like from being damaged by being struck by a hammer by mistake when a core bar 2 of an anchor A is struck into the anchor main body 1. SOLUTION: The core bar 2 is inserted and hidden in an insertion hole 3 formed on the anchor maim body 1 before driven in the same. A strike bar 4 of a driving tool T attached on a hammer drill H is butted on the core bar 2 and the core bar 2 is struck. The core bar 2 is driven into the anchor main body 1, and the core bar 2 expands diameter of a reduced diameter part 3 to show anchor effect. In this drive, only the core bar 2 is struck since the strike bar 4 does not easily come off of the insertion hole 3. There is a little risk of striking the anchor main body 1 and a lining plate 10 or the like by mistake and damaging the same. Also, variation of drive depth for each application can be eliminated and stable anchor effect can be provided by providing a stopper 6 preventing the strike bar 4 from being driven to predetermined depth or more.
