PROBLEM TO BE SOLVED: To shorten a length of a path required for a liquid rubber that has flowed out from the other axial end of a first mold to reach a visible position, compared with that of a structure which distributes the liquid rubber which flowed out from the other axial end of the first mold only through a groove formed along the axial direction on an inner peripheral surface of a cylindrical part of a second mold.;SOLUTION: A mold comprises: a first mold which has a cylindrical shape surrounding a core member and in which a liquid rubber is injected between one axial end and the core member; a second mold mounted on the other axial end of the first mold and having a cylindrical part surrounding the other axial end, and a flow pass formed in the second mold and having a penetrating part penetrating from an inner peripheral surface to an outer peripheral surface of the cylindrical part and circulating the liquid rubber flowed out from the other axial end.;SELECTED DRAWING: Figure 3;COPYRIGHT: (C)2019,JPO&INPIT
