Abstract: A vehicle loads at least one of a plurality of upper units having space to store a person or an object on an under unit including a drive mechanism that rotates wheels in the vehicle. The vehicle includes an under unit including a drive mechanism that rotates wheels and the at least one of the plurality of upper units loaded on the under unit. The under unit includes a loading unit, on which the at least one of the plurality of upper units as described above can be loaded. Each of the plurality of upper units includes a joint that joins to a different upper unit that is adjacently loaded.

Abstract: In the disk clamping mechanism of the present invention, a turntable has a columnar section capable of fitting a disk-shaped medium and a circular supporting section capable of supporting the disk-shaped medium. A damper has a circular pressing section and is magnetically drawn toward the turntable so as to hold the disk-shaped medium. A circular hole is formed in the columnar section of the turntable. A positioning boss is provided in the bottom face of the clamper and inserted into the circular hole. An outer circumferential face of the positioning boss is formed into a tapered face. The tapered face contacts an inner edge of the circular hole when the clamper is held on the turntable on which no disk-shaped medium is mounted. The insertion of the positioning boss into the circular hole is stopped when a distance between the pressing section of the clamper and a supporting section of the turntable is shorter than thickness of the disk-shaped medium.
