Each of the plurality of rollers 11 is formed cylindrical while including a plurality of through holes 11b on a peripheral wall 11a, and is mounted freely rotatable to the truck section 12 via a supporting shaft which is provided coaxially with the center axis thereof. The plurality of rollers 11 are disposed in parallel with each other so as to form a right angle with a traveling direction (a direction of an arrow D) of the truck section 12. <P>COPYRIGHT: (C)2013,JPO&INPIT |
