<p><P>PROBLEM TO BE SOLVED: To solve problems wherein a caliper body moves in the direction of rolling stock width when rolling stock runs, thereby causing wear of a lever turn part, a spring cylinder and a lever interfere with other section, thereby causing noise, and an interference section is damaged in a conventional brake caliper device for railroad rolling stock provided with a parking brake mechanism for swinging the lever supported on the caliper body by the non-restraint spring cylinder and pressing a brake block against a disc by a pressing piece connected with a point of application of the lever. <P>SOLUTION: This brake caliper device is provided with a cylindrical case 18a joined with the caliper body 2, a pin 18b inserted into the cylindrical case, an elastic body 18c giving slide resistance to the pin 18b, and a travel resistance imposing means 18 provided with faces 18d, 18e on which both ends of the pin 18b are abutted. Travel resistance is added to the spring cylinder 13 constituting the parking brake mechanism 10 by the travel resistance imposing means 18 to suppress free moving of the spring cylinder by receiving lateral gravity acceleration when the rolling stock runs and suppress its moving by exceeding fixed amount. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
