PROBLEM TO BE SOLVED: To provide an injection molding method which can facilitate the mass production of a buckle which can fit a belt surely irrespective of its thickness and prevent its careless loosening surely. SOLUTION: The moving direction of a movable mold 92 in clamping/opening a mold 90 in accordance with both inclined surfaces 53, 63 formed in a support bar 50 and a press-fitting bar 60 is slanted to a parting line P on the periphery of the cavity C of the mold 90, and the ejecting direction of a product when it is taken out from the mold 90 is also slanted similarly to the parting line P.
