PROBLEM TO BE SOLVED: To provide a walking type implement capable of suppressing core shift even if a large plowing load arises at the engagement of a side clutch installed between a wheel shaft for linking a plowing shaft and a driving part. SOLUTION: This walking type implement is provided by including the driving part 29, a first inner projecting part 35 at one side of the wheel shaft and a second projecting part 39 at the other side at the position of a first radius R1 from the rotary center of the wheel shaft, including the driving part 29, a first outer projecting part 36 at the one side of the wheel shaft and a second outer projecting part 40 at the other side at the position of a second radius R2 which is larger than the first radius R1, from the rotary center of the wheel shaft, constituting the side clutch so that the first inner projecting part 35 with the second inner projecting part 39, and the first outer projecting part 36 with the second outer projecting part 40 engage, and setting the first radius R1 and second radius R2 so that the first inner projecting part 35 with the second outer projecting part 40 approach or make a contact and the second inner projecting part 39 with the first outer projecting part 36 approach or make a contact.
