2. Description of the Related Art As a crane of this type, the applicant of the present invention has a bracket fixed to one side of a carrier of a vehicle and a bracket rotatably mounted on a bracket through a hollow main shaft. We have applied for a utility model registration for a vehicle crane in which the supported outer boom is configured to be able to turn up and down by the expansion and contraction of a jack, and the inner boom is housed so that it can be pulled out to the outer boom (Japanese Utility Model Application No. 3-73897). In this crane, a pulley is attached to a tip of an inner boom, and a hook is fixed to a tip of a wire routed from a winch provided on a cargo bed to a tip of the inner boom through a main shaft and a boom. A receiving member is provided upright on the other side of the carrier opposite the supporting member, and a concave portion is formed at the upper end of the receiving member so that the tip of the inner boom stored in the outer boom can be inserted therein. A locked device to be locked is provided.

When using this crane, the wire is first loosened to remove the hook from the locked object, the boom is raised, and the tip of the inner boom stored in the outer boom is detached from the recess. Next, the main shaft is turned so that the hook is located substantially at the center of the carrier, and the boom is made substantially horizontal. Further, in this state, the wire is extended, the inner boom is pulled out from the outer boom, and the boom is raised again. When the vehicle travels without using the crane, the procedure is reversed, and the wire is tensioned while the hook is locked to the locked member. As a result, the appearance of the crane is improved, and the crane functions as a roll bar that protects occupants in the cab when the vehicle overturns.

On the other hand, there are known wagon-type automobiles and the like in which a high-mount stop lamp is mounted on the upper surface of the rear end of a roof panel. This lamp has an opening formed on the back of a bowl-shaped case attached to the top of the rear end of the roof panel. A lens is attached to this opening, and a bulb as a light source housed in the case passes through the lens. And emits light behind the vehicle.
