To enable stable sieve work on a wheelbarrow and carry earth and sand without transferring them to simplify sorting work of earth and sand etc.

Holes are bored on both side faces of a wheelbarrow main body 1 as bearings 2, and a sieve bar 3 is inserted into the holes. A sieve tool 4 is placed on the sieve bar 3 to enable sieve work. Each of the bearings 2, the sieve bar 3 and the bottom of the sieve tool 4 has grooves 5 to be engaged with each other. This eliminates friction between the sieve tool 4 and the sieve bar 3. A ball bearing is provided inside the bearing 2 to smooth rotation of the sieve bar 3.
