<p>PROBLEM TO BE SOLVED: To judge the position of the right/left ends of a car briefly and prevent an accident previously by arranging an index, matched with the extension line of the left end and/or right end of a vehicle shown imaginatively on the front glass surface of the frontside of an operation seat, for indicating the end position of the vehicle on a dash board. SOLUTION: A support rod 3 slidable in right/left directions by inserting a left rod 1 to a right rod 2 is provided and slide grooves 1a, 2a for moving index rods 4, 6 are engraved to the support rod 3. In the bottom of the support rod 3, a spread layer of an adhesive and bonding agent for fixing the dash board is formed or a male or female combination piece is arranged on the dash board and the male or female combination piece is arranged on the bottom of the support rod. Index rods 4, 6, matched with the extension line of the left end and/or right end of the vehicle shown imaginatively on the front glass surface of the frontside of an operation seat are arranged, for indicating the end position of the vehicle are arranged near the right/left ends of the support rod 3.
