PROBLEM TO BE SOLVED: To attach a worm, a wheel and a shaft to a transmission case while preventing slip-off in a good assembling property by minimal parts. SOLUTION: In the tending machine 10, a wheel 34 is attached to a tilling shaft 71 for a tillage tine and wheel 34 is engaged with a worm 33 and a shaft 35 is extended from one end of the worm 33 and the shaft 35 is connected to an engine 11. The worm 33, the wheel 34, the shaft 35 and the centrifugal clutch 20 are collectively housed in a transmission case 40. One opening 43 for inserting the worm and the wheel into the transmission case is opened in the transmission case and the opening is sealed with a lid 60 and the lid 60 is served also as a member for preventing slip-off of the worm.
