PURPOSE:To increase a linear region of amplitude and to reduce the strain by providing minute corrugation along a boundary line where an inner circumference stuck side, an outer circumference stuck side and a V-shaped rib contact with each other. CONSTITUTION:For a supporter 8, a number of V-shaped ribs having a pair of faces formed between a peak line 11 and a bottom line 12 extending from the side 9 to the sides 10 in approximating to the are tangent are formed consecutively in the circumference direction and between an inner circumference stuck side 9 fixed to a vibration system and an outer circumference sutck side 10. Minute corrugations 25 and 26 are provided along a boundary line where the sides 9 and 10 and the V-shaped rib contact with each other to absorb the expansion/contraction of the supporter 8 by the V-shaped rib to eliminate the strain and to obtain a high drag against the horizontal dislocation of the vibration system. At the same time, the linearity of vibration in a large amplitude region is improved owing to the corrugations 25 and 26. |
