  By the way, the insertion force when the tool is inserted into the recess (or the pressing force when the tool is pushed into the recess) and the pulling force when the tool accommodated in the recess is pulled out from the recess are within a predetermined range. In order to achieve this, there is a case where it is desired to change the amount of protrusion to the inside of the pair of holding portions, for example, in units of 0.1 mm. However, it has been difficult to correct the portion that forms the holding portion of the mold by shaving or building up in units of 0.1 mm. By the way, it is possible to adjust the protrusion amount of the holding part by cutting out the part forming the holding part of the mold and attaching the piece mold part configured to the desired size to the mold by welding etc. This is not only very troublesome, but also reduces the strength of the mold by cutting out the part that forms the holding part of the mold, and there is a problem of durability, so there is room for improvement.

  Therefore, the present invention has been made in view of such circumstances, and it is an object of the present invention to provide a mold apparatus that can easily change the amount of protrusion of the foamed synthetic resin body to be molded inside the holding portion. To do.
