A power transmission structure capable of attempting miniaturization and weight reduction of small tillers. A small tiller comprising a transmission case bent substantially in a doglegged shape as seen in a side view and interlocked with a prime mover, a traveling section disposed in the front of the transmission case, and a tilling section disposed in the rear of the transmission case, wherein the drive shaft of the transmission case is interlocked with the output shaft of the prime mover through a speed change mechanism, and an axle for driving the traveling section and a tilling shaft for driving the tilling section are individually interlocked with the drive shaft of the transmission case, so that the power from the prime mover is transmitted from a single drive shaft of the transmission case to the traveling section and tilling section.
