In order to mold a connector equipped, on an outer peripheral surface thereof, with an annular groove and a rib (5), a molding die (100) has: a first die block (10) for molding one-half of the region of the outer peripheral surface and the annular groove; a second die block (20) for molding a region on one side of a region other than the region formed by the first die block (10); and a third die block (30) for molding a region on the other side of the region other than the region formed by the fist die block (10). A dividing surface (28) of the second die block (20) and a dividing surface (39) of the third die block (30) which abut each other are each formed at the abutting position in a normal direction to a concave surface (22) of the second die block (20) and a concave surface (32) of the third die block (30) for molding an outer peripheral surface (2a). |
