The damper fastening bolts 22 for fixtures are screwed into the thread holes 21a of the damper fastening fixture 21 to press a front associating plate 4 to compress a first damper 6. The damper fastening bolts 24, 24A, and 24B are screwed into the threaded holes 23a, 23Aa, and 23Ba of the damper fastening portions 23, 23A, and 23B to press a rear associating plate 5 to compress a second damper 7.
