PROBLEM TO BE SOLVED: To enhance the durability of a side clutch device by stabilizing the performance thereof provided in a travelling transmission device, and to reduce manufacturing cost by enabling the side clutch device to be assembled from the outside of a transmission case in the assembling process during manufacturing. SOLUTION: The travelling transmission device is constituted such that right and left side clutch chambers (6, 6) are provided outside of side clutch gears (4, 4) on both sides of a center gear (1), which is rotatably attached to a side clutch shaft (2), independently from the other transmission chamber (5) in the transmission case (3). The right and left side clutch chambers (6, 6) are built-in with hydraulic side clutch devices (7, 7). Cap-type cases (8, 8) are attached from the outside to cover the shaft ends of the side clutch shaft (2) and to support bearings. COPYRIGHT: (C)2011,JPO&INPIT
