<p>PROBLEM TO BE SOLVED: To surely hold each individual brake lever in a symmetrically opened state in time of releasing the brake even if a gap produced by wear in brake lining is controlled so as to be automatically reduced by a lining automatic wear controlling device, at a time when this brake lining is worn out. SOLUTION: A disk braking device overhangs a stopper 58 screwed with an adjusting bolt 56 in the vertical direction, to the outside, attaching it to the lower end side of a brake lever 3A at the side receiving a leaning force in time of opening operation. In addition, a pedestal 59 is installed on a base plate 1 just under the stopper, and a pinion 61 is externally fitted in an upper end of the adjusting bolt 56 via a one-way clutch so as to make the bolt 56 rotatable only in a direction tightening it downward, and it is engaged with the pinion 61 with the specified backlash and a rack 57 extending in the rocking direction of the brake lever 3A is supported from the side of the base plate 1.</p> |
