CONTACT PRESSING MATERIAL SUCH AS RESISTANT ROD IN TILLER

PROBLEM TO BE SOLVED: To obtain a forcedly pressing member for a resistance rod, etc., in a tiller capable of upward and downward adjusting and positioning the resistance rod, etc., with a light operation force and not bringing the resistance rod, etc., to unstable state even when a working resistance varies. SOLUTION: In a tiller installed with an engine in front part of a machine body, a rotary tiller A in the rear part of the machine body and a handle above the rotary tiller A, a mission case 6 is installed between the engine and the rotary tiller A and the middle part of the mission case 6 is fixed with the front part of a rotary cover 14. The rear part of the mission case 6 is fixed with a supporting material 15 which penetrates through a resistance rod 21, etc., the supporting material 15 is fixed with the rear part of the rotary cover 14, positioning members which determine the placement of upper and lower positions of the resistance rod 21, etc., by engagement are installed to the supporting member 15 and the resistance rod 21, etc., and a forcedly pressing member which presses the resistance rod 21, etc., in the direction of its displacement by working resistance is installed.
