A throttle valve wheel (32) comprising: a wheel body (34); a flange portion (57) on the outer peripheral portion of which a toothed portion (80) and a non-toothed portion (83) are formed; anda concave portion (91) formed on the flange portion (57) at a position radially inward from a boundary region (90) between the toothed portion (80) and the non-toothed portion (83) and extending in the circumferential direction of the flange portion ( 57), the flange portion (57) having an arcuate through hole (93) formed in the flange portion (57) through the thickness thereof and in series with the end portion of the concave portion (91) on the non-toothed side The portion (83) extends to serve as a distance adjustment portion, wherein the wheel body (34), the toothed portion (80), the non-toothed portion (83) and the concave portion (91) are formed of resin and by injecting molten resin are molded together via at least a pair of injection ports (95) of a mold (100), the non-toothed area (83) including a fused area (116) formed by resin formed around the concave The region (91) has flowed around along a first flow path (Y1) and resin has flowed along a second flow path (Y2), and the first flow path (Y1) takes a detour via the toothed region (80) side to the concave portion (91), and the second flow path (Y2) takes a detour over the side of the non-toothed portion (83) to the concave portion (91) such that the first and second flow paths (Y1; Y2) meet at the fused area (116).
