PURPOSE:To improve the riding quality of a vehicle by a method wherein a chamber part is formed within an elastic body and the negative suction pressure of an internal-combustion engine is led in the chamber part in order to control the distance between a magnet and an armature by said negative pressure. CONSTITUTION:A chamber part 20 is formed within an elastic body 10 and the negative suction pressure of an internal-combustion engine is led in the chamber part 20 in order to control the distance between a magnet 15 and an armature 19. Consequently, effective attraction force is obtained, resulting in enabling to keep the spring constant of a mount lower over a wide frequency range. Accordingly, the remarkable improvement of the riding quality of a vehicle is resulted. |
