<p><P>PROBLEM TO BE SOLVED: To provide a carriage capable of keeping a high turning performance without degrading progressive performance even when the carriage runs on a running surface where irregularity exists. <P>SOLUTION: This carriage includes an energization mechanism 40 for supporting auxiliary running wheels 31A, 31B to be capable of approaching/separating to/from a mounting base 10, and energizing the auxiliary running wheels 31A, 31B toward the running surface by elastic force of springs 41. The energization mechanism 40 includes a lower-limit stopper 64 for limiting a maximum separation distance when the auxiliary running wheels 31A, 31B are separated from the mounting base 10 by the elastic force of the springs 41, and a mounting hole for adjusting the maximum separation distance. <P>COPYRIGHT: (C)2012,JPO&INPIT</p> |
