<P>PROBLEM TO BE SOLVED: To effectively restrict the deviation of an upper chuck with respect to a revolving shaft of a lower chuck due to separating force. <P>SOLUTION: A tire testing device 1 includes: vertical frames 30a, 30b supported by a lower frame 20; a vertically movable beam 40 laid between the vertical frames 30a, 30b; an upper chuck 45 attached to the center in the longitudinal direction of the beam 40; a lower chuck 25 attached to the lower frame, and the like. The beam 40 is lowered from an upper standby position and fixed in a state that the upper and lower chucks 25, 45 are engaged with each other to hold a tire 10. In a view in a vertical direction, a revolving shaft 45x of the upper chuck 45 and support points 30x of the beam 40 at the vertical frames 30a, 30b arranged at equal intervals from the revolving shaft 45x placed therebetween are aligned on a straight line. <P>COPYRIGHT: (C)2012,JPO&INPIT |
