Abstract

PURPOSE:To simplify constitution by installing the ring body for speed change of a subtransmission part for traveling onto a power taking-out shaft in slidable ways, permitting integral revolution, and installing an interlocking connection part of the transmission shaft for wheel onto the front edge side. CONSTITUTION:The ring body 55 for speed change of a subtransmission part 13 is installed in slidable ways, permitting the integral revolution, through the spline engagement onto a power taking-out shaft 5, and a transmission gear part 14 as the interlocking connection part for a transmission shaft 7 for wheel is installed at the front edge part of the power taking-put shaft 5. Therefore, the output of the subtransmission shaft 13 is transmitted through the integral revolution of the ring body 55 for speed change and the power taking-out shaft 5, and the revolution speed of the power taking-out shaft 5 varies, accompanied by the traveling speed change. Since the power taking-out shaft 5 is utilized as the output shaft of the subtransmission part 3 in this constitution, structure can be simplified.
