PROBLEM TO BE SOLVED: To provide a rotary tiller protecting a grease nipple from being damaged by collision or the like to other things and so forth. SOLUTION: In the rotary tiller, a grease injection port 104 is opened backward and slightly downward, so grease injection operation to the grease nipple 100 disposed in the grease injection port 104 is simply and certainly carried out from backside of the rotary tiller A and the grease nipple 100 is protected from being damaged by collision or the like to other things, as it is disposed in a support body piece. Moreover, as a buffer piece 89 and the grease nipple 100 are housed/disposed in a concave housing space 93 formed in the support body piece, the buffer piece can certainly prevent slippage of location, dropping out and the like and the grease nipple 100 can be certainly protected owing to certainty of buffer function of the buffer piece 89 in a good state.
