PROBLEM TO BE SOLVED: To sufficiently change the intrarow spacing by a change in one site even in the case of a transplanter for many levees and provide a mechanism for changing the intrarow spacing of the transplanter with few chain wheels for exchange in relation to the mechanism for changing the intrarow spacing of the transplanter for the many levees for changing the seedling spacing into various planting intrarow spacings and transplanting seedlings in transplanting cultivation of field crops. SOLUTION: This mechanism for changing the intrarow spacing for a transplanter is capable of changing the planting intrarow spacing by changing the speed change ratio of a speed changing mechanism 61 of an intrarow spacing changing power mechanism 60, making a planting device power mechanism 50 and the intrarow spacing changing power mechanism 60 transmit a power to plating devices 30 and feeding devices 20 in plural sites and installing the speed changing mechanism 61 of the intrarow spacing changing power mechanism 60 in one site.
