Magnetic block toy

A magnetic block toy comprising a plurality of blocks coupled to one another by means of a magnetic force, wherein the magnetic block includes:

• a generally coin-like magnet having N and S poles arranged on the upper and lower surfaces thereof;
• a magnet-mounting part having a cylindrical case for allowing the magnet to be mounted at the center thereof and a shaft formed integrally on opposed both sides of the outer periphery of the cylindrical case;
• and a body part consisting of two half bodies connected together, the body part having two or more end portions, each end portion having a shaft-fixing portion formed on the inner periphery thereof so as to fixedly support the shaft of the magnet-mounting part thereto, and a space portion formed at the inside thereof so as to internally house the magnet-mounting part supported by the shaft and the shaft-fixing portion to cause the magnet-mounting part to pivotally rotate therein, wherein protrusions and indents are formed alternately at equal intervals or concavo-convexes are formed continuously in a radial shape on both end edge surfaces of the body part, so that when the body parts of adjacent magnetic blocks are coupled to each other by means of the magnets, the both end edge surfaces of the body parts abutting against each other are prevented from being slipped by means of the protrusions and indents or the concavo-convexes.
