Claims

[Claims for Utility Model Registration] 1. A drive shaft 1 on the engine E side and a driven shaft 2 on the transmission case W side are interlocked and connected via a ball joint mechanism B, and both shafts in the ball joint mechanism B One of the engagement recesses 16a and 16b of the transmission roller 15 provided over the shafts 1 and 2 has a circumference that allows relative rotation within a certain small range in the circumferential direction of both shafts 1 and 2. The ball joint mechanism B is provided with an elastic body 18 that urges the transmission roller 15 to an intermediate position of the flexible engagement recess 16b. In the transmission structure of agricultural machinery, the transmission roller 15 is connected to the flexible engagement recess 16.
A power transmission structure for a mobile agricultural machine in which an elastic body 18 biasing to the intermediate position of b is formed by a single ring-shaped spring fitted onto the shaft. 2 The elastic body 18 has a flexible engagement recess 1
2. The power transmission structure for a mobile agricultural machine according to claim 1, wherein the transmission structure is a single ring-shaped spring externally fitted in an outer circumferential annular groove 17 formed on the bottom surface of the movable agricultural machine. 3. The transmission structure for a mobile agricultural machine according to claim 1, wherein the elastic body 18 is a single coil spring externally fitted over the driving shaft 1 and the driven shaft 2 which are fitted to each other.
