To eliminate preparation work or arrangement miss of a spacer and troublesome maintenance control for the spacer by reducing the number of spacers for filling the excess space in a vulcanizing mold and to enhance heat efficiency at the time of vulcanization.
The vulcanizing mold is equipped with upper and lower frames 11 and 12, left and right front and rear side frames 14 provided between the upper and lower frames 11 and 12, the side plates 15 provided on the inside of the side frames, a placing plate 16 having a quadrilateral shape on a plan view and placing a non-molded vibration-proof rubber support 1 and the top plate 17 interposed between the upper frame 11 and the vibration-proof rubber support 1, and the upper and lower frames 11 and 12 are pressed to vulcanize and mold the vibration-proof rubber support 1. The adjacent side plates 15 and 15 are successively arranged in an almost T-shape on a plan view in a contact state and the opposed side plates 15 and 15 are moved in parallel to the diagonal line L of the arranging space S of the vibration-proof rubber support 1 corresponding to the size of the vibration-proof rubber support 1 to be vulcanized so as to approach and separate each other.
