Topic The configuration component of the top and bottom slipping to especially direction of rotation with the earthquake which collapses easily even the occasion being relatively big earthquake and the like, iterates, twist, with the simple configuration which does not have the kind of times when it occurs, the stone make monument whose assembly job on site is easy is offered.SolutionsIt consists of the configuration component of 5 stones make to the lawn base, the medium base, the upper base, the sun/size wheel and the pole stone which it stacked, in lower part of the configuration component of the upper part which each it rises and falls adjoins tenon 7 for join, each it forms mortise 6, on top of the configuration component of the lower part, configuration component mutual each it rises and falls adjoins, it joins the tenon 7 for join of configuration component of upper part by the fact that it fits to the mortise 6 of the configuration component of the lower part. Tenon 7 for join constituted, charging this in mortise, 6 when it turns counterclockwise, in order for the revolution to halt at angular position of 45 degrees, in order for specified position of tenon 7 for join this to touch to the stopper 6a1 of mortise 6, came out at that position and in order to stop, formed the engagement space 6a in mortise 6.
