PURPOSE:To prevent the damage of the titled heat exchanger by controlling a shearing stress generating in an elastomer in the circumferential direction by a method wherein the drive force of a ring gear is transmitted to a core through the elastomer provided on the inner peripheral surface of the ring gear and projections on the outer periphery of the core. CONSTITUTION:The projections 12 and the projections 11 are provided on the inner peripheral surface of the ring gear 2 and the outer periphery of the core 1, respectively, so that each of the projections 12 and each of the projections 11 make a pair and extend outward to overlap each other in the radial direction and the elastomer 13 is interposed at least between each of the projections 12 of the ring gear and each of the projections 11 provided on the drive side of the projection 12 so as to make a pair therewith. With the above structure, when the core 1 is driven, the drive force of the core 1 in the circumferential direction is transmitted from the projections 12 to the projections 11 through the elastomer 13 and as a result, only a compressive stress generates in the elastomer 13 at a part E so that the generation of the shearing stress is controlled and the durability of the elastomer is improved. |
