PROBLEM TO BE SOLVED: To provide a post cone which enables position detection by a vehicle-type drawing device to become more accurate. SOLUTION: When a vehicle-type drawing device 1 detects its own position by a laser radar 2 mounted thereon, a post cone is provided in which a pipe part 9 is mounted on a spherical surface part 8 of a support part 7 installed on a base part 4, and a lid part 11 is fitted on an upper end of the pipe part 9, and a penetration shaft 13 is penetrated from under the base part 4 or the support part 7 to above the lid part 11, and the penetration shaft 13 is pulled upward by a cam lever 15 installed on an upper portion of the penetration shaft 13 so that the pipe part 9 is pushed to the support part 7 and fixed thereto. Loosening the cam lever 15 allows an inclination of the pipe part 9 to be adjusted along the spherical surface part 8 of the support part 7. When the inclination of the pipe part 9 is adjusted such that a level 12 installed on the lid part 11 indicates a horizontal situation, the pipe part 9 becomes vertical and thus the vehicle-type drawing device 1 can accurately detect its own position by using the laser radar 2.
