Abstract
A spindle supporting box structure, wherein longitudinal parts forming both ends of lateral parts at each of right and left longitudinal side faces facing, with a spindle therebetween, in a direction almost perpendicular to longitudinal side faces facing in a front-back direction are formed by longitudinal tubular members having suitable flexural rigidity. A damping structure wherein required frameworks of structures are formed by tubular members and wherein concrete is filled in the tubular members and then solidified. As an alternative, a powdery damping material or a jelly damping material is airtightly sealed in the tubular members. An inner space of one or more of the tubular members is made into a gas pressurized tank wherein a balance cylinder is connected to the gas pressurized tank and wherein the gas in the gas pressurized tank directly acts on a cylinder chamber of the balance cylinder.
