A rotating force transmitting/blocking device for assembly-type toys is provided to transmit rotating force between rotary shafts by using a rotary gear, to cut off the rotating force by separating a combining member from the rotary gear, and to transmit the rotating force to the other rotary gear by turning only the rotary gear. The rotating force transmitting/blocking device for assembly-type toys, using a rotary shaft(20) having a longitudinal groove(21) on the outer peripheral surface is composed of a rotary gear(10) having a center through-hole(11) penetrated by the rotary shaft, gear teeth(12) formed on the outer peripheral surface, and a projection support unit(13) formed on one side of the center through-hole and a combining member(30) comprising an opening part(32) covering the outer peripheral surface of the rotary shaft and having a combining projection(31) formed at the inside and engaged with the longitudinal groove and a support projection(33) formed on one side of a rear end of the opening part and joined with the projection support unit of the rotary gear. |
