| description | Provided is an expansion-type anchor with excellent pull-out strength. The anchor comprises an anchor body 1 that has an expansion section 3 split by an inner slit 2, and a sleeve 9 to enclose and hold the expansion section 3 of the anchor body 1. The sleeve 9 is split into a plurality of follower expansion sections by an outer main slit 10 and an outer auxiliary slit 11. A group of balls 4 is disposed inside the anchor body 1, and the expansion section 3 expands into a tapered shape when the group of balls 4 is pressed by an expansion bolt 6. When a pull-out force is applied to the anchor body 1, the sleeve 9 does not retract and deforms by expanding after the retraction of the anchor body 1. As a result, the anchor body 1 is prevented from retracting by way of the sleeve 9 being sandwiched between a prepared hole 13 and the expansion section 3. |
