Provided is a tire molding apparatus capable of preventing a transfer device from continuing to swing after stop. The tire molding apparatus includes: a rail; and a transfer device configured to hold a tire member and move along the rail. The transfer device is configured to move along the rail and stop to receive or deliver the tire member. A positioning device is provided in the transfer device. The positioning device includes a concave portion and a convex portion. One of the concave portion and the convex portion is provided in the transfer device, and the other one of the concave portion and the convex portion is provided at a position facing the transfer device when the transfer device is stopped. The transfer device is stopped by fitting the concave portion to the convex portion.
