PROBLEM TO BE SOLVED: To attach a clutch of a tending machine or a first rolling bearing for supporting the clutch to a transmission case while preventing slip-off in good assembling property by minimum parts. SOLUTION: In the tending machine 10, a wheel 34 is attached to a tilling shaft 71 for attaching a tillage tine and wheel 34 is engaged with a worm 33 and a shaft 35 having a size smaller than that of the worm 33 is extended from one end of the worm 33 and the shaft 35 is connected through a centrifugal clutch 20 to an engine 11 in which rotation direction is only one direction R2. The worm 33, the wheel 34, the shaft 35 and the centrifugal clutch 20 are collectively housed in a transmission case 40. A first bearing 51 for preventing transfer of the centrifugal clutch 20 to the worm side and a second bearing 52 for preventing transfer of the worm to the centrifugal clutch side are provided in the transmission case 40 and the shaft is connected to the centrifugal clutch by a screw and fastening direction of the connection by the screw is made to coincide with the rotation direction R2 of an engine.
