A pair of anti-vibration springs 11 are provided on one side of the apparatus 1 between the side surface 3a of the support frame 3 and the side surface 2a of the outer casing 2. The side surfaces 2a and 3a are surfaces that do not have a top-to-bottom relationship when the device 1 is placed horizontally or vertically. These vibration-proof springs 11 absorb the vibration of the support frame 3 when the vehicle vibrates in cooperation with the damper 4. The lower end of the anti-vibration spring 11 is rotatably mounted on a support shaft 10 fixed to the side surface 3a of the support frame 3, and the upper end of the anti-vibration spring 11 is rotatably mounted on the side surface 2a of the outer casing. It is fixed to the protruding end portion 12a of the rotating plate 12, which is an indirect member . As shown in FIGS. 1 and 2, the rotating plate 12 is pivotally attached to the side surface 2a of the outer casing 2 by a supporting shaft 13, and the rotating plate 12 is point-symmetric with respect to the supporting shaft 13. Arc-shaped openings 14 and 15 are provided. These arc-shaped openings 14 and 15 are formed over an angle range of 90 degrees around the support shaft 13, and the arc-shaped openings 14 and 15 have guide shafts 16 and 15 fixed to the side surface 2 a of the outer casing. 17 are engaged with each other. The rotating plate 12 and the outer casing 2
