Abstract

A runnable block including a block body having a first engage projection and first engage recess respectively provided on the top and bottom surfaces of the block body, and four wheels rotatably attached to both sides of the block body via wheel shafts. A part of each wheel of this block protrudes farther downward than a lowermost surface including the lower engage section, and the diameter of each wheel is set approximately equal to the distance from the top of the first engage projection to the bottom of the first engage recess. As one block is coupled to another block by engaging the first engage projection of the former block to the first engage recess of the latter block, the wheels of both blocks mutually contact each other. This contact allows the rotation of one wheel to be transmitted to the other wheel, so that when the coupled blocks run, all the wheels of the blocks rotate.
