The present invention relates to a magnet mounting tool for a magnetic toy, and more particularly, each block is obsessed with the polarity of the magnet in a state in which it is made of a specific structure including a permanent magnet and is embedded and installed on each side of a magnetic toy having a block shape. It relates to a magnetic mounting hole for magnetic toys that enables mutual coupling without this.

As is well known, magnet toys combine a magnet to a linear, panel, block, or the like unit constituent member, and then assemble the unit constituent member into a three-dimensional three-dimensional structure having a predetermined shape by using the magnetic force of the magnet. made so that

As an example of the magnetic toy, there is a block-type magnet toy made of a hexahedron made of wood or plastic. It is configured to be able to assemble a three-dimensional three-dimensional structure having a predetermined shape through surface coupling between block-type magnetic toys.

At this time, when the permanent magnet is fixed to the surface of the block and its polarity is the same in relation to the permanent magnet fixed to the other unit block coupled thereto, a repulsive force, not an attractive force, is generated so that the unit block members are coupled together. This becomes impossible, and if the polarity is confirmed, assembly between unit block members must be performed, resulting in a problem in which the degree of assembly freedom is reduced.
