PROBLEM TO BE SOLVED: To provide a vibrationproof hanger device which is adapted to rigidly support a supported object material in construction stage and can convert into the vibrationproof support after construction is completed and can easily convert by restoring to the rigid support when changing to the vibrationproof spring. SOLUTION: The device includes a housing 13 fixed to building side, the vibrationproof spring 21 interposed between the housing and a supported object material 7, a suspension member 16 into which the vibrationproof spring is fitted, a tensional means 20 for allowing for deflection on the vibrationproof spring 21, a flange part 19 provided on the suspension member 16 and a spacer 23 removably interposed between the flange part and the housing 13. The device is characterized in that it is adapted to directly suspend and support the supported object material 7 by interposing the spacer 23 between the housing 13 and the flange 19, and allows for predefined deflection by the tensional means 20 by setting the vibrationproof spring 21 after the construction is completed and thereby, eliminating the spacer 23 by enlarging spacing between the housing 13 and the flange part 19, and the supported object material 7 is adapted to vibrationproof support by the vibrationproof spring 21.
