PURPOSE:To dispense with the necessity of providing an early tensile load regulator to improve impact damping property and reliability simply and economically by constituting an elastic annular tube interposed between and interconnecting an inner ring and an outer ring while having compressed air in the interior. CONSTITUTION:An elastic annular tube 7 is interposed between inner and outer rings 1, 4 and formed of rubber tube for example. The inner ring 1 is formed on the outer periphery with an annular groove 8 and the outer ring 4 is formed on the inner periphery with an annular groove 9. The inner and outer peripheral portions of the tube 7 are fitted in these annular grooves 8, 9 so that the inner and outer rings 1, 4 are interconnected through the tube 7. The tube 7, like a tire tube, is provided with an air pouring portion 10 having a valve through which air is forcibly poured into the tube 7 to provide the internal pressure so that the tube is expanded to interconnect the inner and outer rings 1, 4. Thus, an early tensile load regulator is dispensed with to reduce production cost while the elastic tube provides an impact damper to absorb vibration and impact and provide a smooth running of a driven shaft for elongating its life. |
