Counterbored holes (44) are formed to a depth such that inclined surfaces (412) are positioned higher than the upper ends (721) of disk-like members (72) of the bolts (7). It is difficult for a thief to apply shocks to disk-like members (72) of the bolts (7) by means of a sharp tool. Therefore, it is difficult to turn the bolts (7) to loosen the same.
