To provide an aseismic supporting implement improved in assembling workability to press and stick an adhesive surface to an adherend by adjusting the interval between opposed members.

The aseismic supporting implement includes: a pair of upper and lower members 11 and 13 oppositely disposed to each other; adhesive members 33 and 35 provided on the opposite sides of the pair of upper and lower members 11 and 13 and having adhesive surfaces 33a and 35a pressed and stuck to a bottom surface 5 of furniture 3 and a floor surface 7 according to the interval between the upper and lower members 11 and 13; a jack mechanism 15 for coupling the upper and lower members 11 and 13 and adjusting the interval between the upper and lower members; and an adjusting screw portion 17 disposed to cross the sticking direction of the adhesive surfaces 33a and 35a, driving the jack mechanism 15 according to the axial rotation, and adjusting the interval between the upper and lower members 11 and 13.
