Abstract:
PROBLEM TO BE SOLVED: To improve maneuverability by making a sled body slide or travel with a wheel without performing a switching operation every time to put in/out the wheel and to change the direction of the sled body smoothly by making the wheel rotate smoothly around a rotary shaft.SOLUTION: The sled body 10, having a bottom wall 11 on which a transportation object is mounted and a surface configured as a sliding surface 12, is provided with the wheel 21 a part of which exposes from the sliding surface 12 and abuts on a ground surface, a base 22, and a castor 20 having a holding body 24 which is attached to the base 22 and holds the wheel 21 so as to make the wheel rotate around the rotary shaft 23 and to hold the wheel at an eccentric position with respect to an axis 23a of the rotary shaft 23. An opening 17 is formed on the sled body 10, and a disk 30 that rotates around the axis 23a of the rotary shaft 23 is arranged in the opening 17. An aperture 31 from which a part of the wheel 21 projects slightly is formed in the disk 30. When the holding body 24 rotates, the wheel 21 locks to the aperture to rotate the disk 30.
