The invention discloses a hand strap guide device on an escalator or a travolater, which comprises a movable hand strap, wherein the cross section of the hand strap is in a C shape, an opening of the C shape of the hand strap is upward, and the guide device also comprises a support frame, a guide shaft and a bearing, wherein the guide shaft is arranged on the support frame, the bearing is sheathed on the end part of the guide shaft, and the axial line of the bearing is in up-down arrangement and is vertical to the moving direction of the hand strap, at least a part of the bearing extends into the opening of the C shape, the bearing is separated from the hand strap when the hand strap is moved normally, the bearing can not influence the normal movement of the hand strap, the outer ring of the bearing is in rolling contact with the tail end of the C shape of the hand strap when the hand strap deviates in the transverse direction, the bearing can guide and correct the hand strap, and in addition, the outer ring of the bearing is in rolling contact of the hand strap, so the hand strap has small friction resistance, and the slippage phenomenon of the hand strap can be avoided. Thereby, possibly occurring safety accidents can be avoided. The resistance of the hand strap is reduced through the rolling friction, the driving force requirement of the hand strap can also be reduced, the noise caused by friction can be reduced, and the service life of the hand strap can be improved.
