VEHICULAR DAMPER DEVICE

摘要

PURPOSE: To simplify structure and thus reduce costs below the levels of an oil damper. CONSTITUTION: A vehicular damper device comprises an outer shell 4, a piston rod 3 capable of reciprocation along the length of the outer shell 4 with the tip inserted in the outer shell 4, a coil spring 7 disposed about the periphery of the outer shell 4 to exert resilience in the direction to pull the piston rod 3 out of the outer shell 4, an inner shell 8 connectedly fixed to the tip of the piston rod 3 and housed in the outer shell 4 so as to reciprocate integrally with the piston rod 3 in the outer shell 4, and a viscoelastic rubber layer 9 arranged between the inner shell 8 and the outer shell 4 and adhesively fixed to the outer surface of the inner shell 8 and the inner surface of the outer shell 4.
