ABSTRACT:
A vibration buffering device is constructed in a lightweight and compact fashion, the number of parts is reduced, the assembling operation can be simplified, and generation of a noise is prevented. An annular passage and accommodating recesses, which open into the passage in pairs, are defined in a damper housing integral with a first mass member. First coil springs are retained on spring holders inserted in the passage, and second coil springs are accommodated in the accommodating recesses. A transmitting arm, placed into the passage, is coupled to a second mass member which is capable of being angularly displaced about the same axis relative to the first mass member. In a power non-transmitting state, opposite ends of the second coil springs are received by opposite ends of the accommodating recesses and are in contact with opposite ends of the spring holders. When a relative angular displacement is produced between both the mass members, the transmitting arm is turned relative to the damper housing, while compressing the first coil springs, so as to come into abutment against one end of the second coil springs.
