To increase the strength of a wheel for agricultural use in which a tire formed of a rubber-like elastic material is fixed to the rim formed in an annular shape by a pipe so as to cover the rim by devising a sectional shape of a rim without increasing the wall thickness of the rim or changing a material thereof.

The sectional shape of a cut pipe constituting a rim 4 in the surface orthogonal to the circumferential direction B of the rim 4 is an elliptical shape in which the direction of a major axis D1 is agreed with the radial direction A of the rim 4, and the ratio D1/D2 of the major axis D1 to the minor axis D2 of the elliptical shape is set to be 1.1 and 1.5.
