Abstract:
A guide wheel shock absorbing device includes an attachment arm, a shock absorbing link provided on the attachment arm and extending in one direction, a shock absorbing link support portion provided on the shock absorbing link and supporting the shock absorbing link in a state of being oscillatable with respect to the attachment arm, a guide wheel coming into contact with a guide rail laid on a traveling track of a vehicle, a guide wheel support portion provided on the shock absorbing link and supporting the guide wheel in a rotatable state, and a shock absorbing elastic portion elastically supporting the shock absorbing link with respect to the attachment arm. The shock absorbing elastic portion has first and second elastic bodies different in displacement with respect to a guide wheel load.
