2. Description of the Related Art Conventionally, in a wooden building, the base is
Since it was laid directly on the top of the cloth foundation, its levelness (level) depended on the construction accuracy of the top of the cloth foundation.
For this reason, it is common today to use pre-cut structural materials and feather pedicels, and if the construction accuracy of the top end of the cloth foundation is low, the error in the levelness of the base remains as it is. It was the cause of the inferior floors on the 1st and 2nd floors and the poor installation of fittings.

As a technique for solving such a problem, a base adjusting plate disclosed in Japanese Utility Model Publication No. 6-20771 is proposed. The base adjusting plate is mainly composed of a pair of wedge-shaped pieces having inclined surfaces which are inclined in opposite directions, and the inclined surfaces are formed with sawtooth surfaces which engage with each other. Then, this base adjustment plate is interposed between the foundation and the base, and the bottom surface of one wedge-shaped piece is hit with a mallet or the like to shift the saw teeth on the sawtooth surface to adjust the base height. It is done like this.

However, the base adjusting plate described in the above publication is provided so as to adjust the height of the base by striking the bottom of the base adjusting plate between the base and the foundation. It was hard to do. Moreover, since the adjustment of the base height depends on the step of the sawtooth surface, there is a limit to the fine adjustment of the height.

Therefore, an object of the present invention is to provide a base height adjuster capable of easily and finely adjusting the base height.
