<P>PROBLEM TO BE SOLVED: To solve a problem of a conventional art, in which it has structure constituted by inserting a support plate (plate) of a wheel unit into a pair of first groove shape parts, a frame member is constituted of the first groove shape parts each having an U-shape when seen from an end face, the second groove parts each having the same shape as the first groove shape part through a connecting part, and a bottom wall connecting the second groove shape parts, the second groove shape parts are disposed to the outside of opening edges of lips of the first groove shape parts, the structure is weak against a load, a trouble is left in efficient dispersion thereof, and troubles are left in insertion/detachment of the support plate and facilitation of assembly work. Ž<P>SOLUTION: The wheel conveyor includes a continuous frame and the wheel unit. The continuous frame includes: the approximately U-shaped receiving groove including upper end sides, an opening, lower end sides, and upper side face parts connecting the upper and lower end sides; inclined continuous parts formed to be continuous to the lower end sides and inclined outward toward the bottom part; lower side face parts formed to be continuous to the inclined continuous parts; and a bottom part connecting the lower face parts. The wheel unit includes: a pair of side face frames inserted into the receiving groove; a plurality of wheels and supported by the side frames; and a plurality of shafts disposed to the bearing recess part.
