The wheel for agricultural use with its rotational direction R during the normal use being designated has an elastic wheel body 3 which is provided with a substantially annular body part 18 and blade plates 16 projected on both sides in the axle direction from the body part and formed of an elastic material. The blade plates are inclined so that inner ends 17 in the radial direction are located on the rotational direction side from its outer ends 20 in the radial direction, and curved in a recessed shape with respect to the rotational direction while the degree of inclination to the rotational direction side is increased toward the outer end in the axle direction from the body part. The ratio (L-r)/r in the relationship of the distance L between the outer ends on both sides in the axle direction in the blade plates to and the width r in the axle direction of the body part is 6, and the angle formed by the line connecting the circumferential intermediate point P2 at a roof of the body part in the blade plates to a circumferential intermediate point P1 on the outer end in the axial direction and the circumferential direction is 75 and 86.
