PROBLEM TO BE SOLVED: To restrain a wheelbarrow from overturning in the longitudinal direction in practicing the wheelbarrow so as to enable safe practice by fitting an arm extended in the longitudinal direction to the frame main body of the wheelbarrow to wrap the tire of the wheelbarrow, and supporting an auxiliary wheel to the lower end of each arm. SOLUTION: A practice tool fitted to a part of the frame main body 5 of a wheelbarrow has a metal fitting 2 formed by providing an iron plate having a bolt hole on both end parts of a pipe two-split member, and the metal fitting 2 is disposed in the outer periphery of the frame main body 5 and temporarily fixed by fastening a bolt-nut 4. A pair of front and rear arms 1, the upper end of which is fixed to the fitting 2, with the auxiliary wheel 3 supported on the lower end, are adjusted in its fitting position so that both of the front and rear auxiliary wheels 1 are separated from the ground about 2 cm, and then the bolt-nut 4 is finally fastened. The arm 1 is formed by an iron-made pipe having satisfactory strength and formed to be freely expanded and contracted in the longitudinal direction at need.
