Abstract: This invention provides a retroreflective sheeting which at least comprises a printed image-incorporated retroreflective sheeting and an optical element array sheet in which a large number of light-transmissive optical elements are regularly disposed at least at a fixed location; more particularly a printed image-incorporated retroreflective sheeting which reveals a stereoscopic image when the printed image is seen through a lenticular lens sheet or a convex lens array sheet; and a reflective sheeting which uses the stereoscopic image for tamper prevention.

Abstract: A hinge structure of a jutting door for a vehicle has a hinge member pivotally attached to between the inside of a vehicle body and a door at the both ends, the hinge member swinging so that the door opens with a forward movement. The door hinge structure comprises a rod member having a length different from that of the hinge member. The rod member is pivotally attached to between the inside of the vehicle body and the door at the both ends so as to restrain an outer end of the door from excessively opening. The hinge member has an avoiding part for avoiding a touch with the vehicle body when the door is fully or near fully open. The hinge part can be arranged on the passenger compartment side which is unaffected by mud, without the hinge part and the rod part protruding into the passenger compartment to obstruct the passenger when the door is fully closed.
