Claim 8

Dependent Claim 177 words

A spring damper device for use in a vibration-damping floor providing a restoring function after a displacement of a floor structure, as well as a triggering function and a damping function during said displacement by supporting horizontally displaceably respective support points of said floor structure on a fixed floor, comprising; (a) a damper main body of a shallow and flat vessel shape mounted on and secured to said fixed floor, (b) a viscous fluid contained by a predetermined amount in said damper main body, (c) a movable member attached to said floor structure, immersed in said viscous fluid and ensuring a predetermined gap between a lower surface of said movable member and a bottom of said damper main body, (d) a rope-like member not transmitting a compressive force and being connected to the other end of said coil spring at one end thereof and connected to said movable member at the other end thereof, and (e) a reaction force receiving roller attached to said rope-like member and abutted against an inner surface of said damper main body.

Claim 9

Dependent Claim 177 words

A spring damper device for use in a vibration-damping floor providing a restoring function after a displacement of a floor structure, as well as a triggering function and a damping function during said displacement by supporting horizontally displaceably respective support points of said floor structure on a fixed floor, comprising; (a) a damper main body of a shallow and flat vessel shape mounted on and secured to said fixed floor, (b) a viscous fluid contained by a predetermined amount in said damper main body, (c) a movable member attached to said floor structure, immersed in said viscous fluid and ensuring a predetermined gap between a lower surface of said movable member and a bottom of said damper main body, (d) a rope-like member not transmitting a compressive force and being connected to the other end of said coil spring at one end thereof and connected to said movable member at the other end thereof, and (e) a reaction force receiving roller attached to said rope-like member and abutted against an inner surface of said damper main body.

Claim 10

Dependent Claim 36 words
