Abstract

A traveling vehicle comprising a straight drive gearbox and a turning gearbox which transmit the power of an engine mounted on a traveling body to the right and left traveling sections after changing the speed, a straight drive operation unit (13) which controls the straight drive outputs from the straight drive gearbox to the right and left traveling sections, and a turning operation unit (10) which controls the turning outputs from the turning gearbox to the right and left traveling sections, wherein the operability of straight drive and turning is enhanced by a small and simple mechanism. A turning input shaft (72) being rotated by means of the turning operation unit (10) is provided with a control body (131) having a cam body (134) extending in the circumferential direction around the turning axis line (P) of the shaft such that the control body tilt-rotates freely around the speed change axis line (S) intersecting the turning axis line (P) perpendicularly by means of the straight drive operation unit (13). The straight drive gearbox is operated for speeed change by a speed changing slip member (157) which engages slidably with that portion of the cam body (134) located on the axis line (W) intersecting the speed change axis line (S) perpendicularly, and the turning gearbox is operated for speed change by a turning slip member (166) which engages slidably with that portion of the cam body (134) located on the speed change axis line (S).
