PURPOSE:To enable solid vulcanizing mold of a rubber elastic body, so as to improve the productivity and reduce the cost by sinking cylindrical mass members disposed between inner and outer cylinder metals, with a void of designated dimensions in the peripheral direction, into a rubber elastic body. CONSTITUTION:In a cylindrical mount device with a dynamitic damper, split mass metals, 18, 18 mold a cylindrical mass member disposed between an inner cylinder metal 10 and an outer cylinder metal 12 are sunk, with voids 20, 20 of designated dimensions in the peripheral direction, into a rubber elastic body 14. The mass member for exhibiting a mount low dynamic spring effect when vibration of a medium to high frequency is input is formed by plural split bodies divided in the peripheral direction, and the voids 20 are provided, so that the elastic body 14 can be formed by solid vulcanizing mold so as to improve the productivity and reduce the cost. |
