ABSTRACT:
The present invention provides a safety device of vibration roller wherein a travel switching device of the roller is switched to a neutral position automatically and the roller stops automatically when the operator is caught between the roller and an obstacle, and a safety switch is activated, even if the travel lever is placed in the reverse position continuously.A back end (16a) of an outer tube of an operation cable (7) is locked in front of the travel lever (4) in the case (2) when a safety switch (22) is not activated, the back end (16a) of the outer tube is released and displaced to a direction of the travel lever (4) when the safety switch (22) is activated.
