PROBLEM TO BE SOLVED: To provide an easily-usable, lightweight and practical spacer for an anchor, which is attachable to the anchor sideways, and can be produced at low costs. SOLUTION: The spacer 1 for an anchor is formed of almost U-shaped mounting sections 3, 4 formed at least one end thereof, and a curved section 2 integrally connected to the mounting sections, and formed almost like a coil with its intermediate portion bulging in a radially outward direction. Then the spacer is mounted sideways on the anchor 6 via openings of the respective mounting portions 3, 4. COPYRIGHT: (C)2006,JPO&NCIPI
