PROBLEM TO BE SOLVED: To facilitate the height adjustment by fastening a roller carrier and an eccentric disc fixed to the roller carrier to a fixing plate for fixation freely to be adjusted in the height direction. SOLUTION: An eccentric disc is supported by a roller carrier 13A of a traveling mechanism 11 freely to be rotated around a shaft A, and a lock screw 19 is passed through a slit-like opening 21 concentrically provided with the shaft A in the carrier 13 so as to be screwed with a female screw of the eccentric disc. At the time of construction, a fixing plate 31 and an extension part 33 thereof are pushed into a barrel-type hole drilled in a sliding door 9, and fixed to the sliding door 9 by a screw through a hole 43. Continuously, the eccentric disc is pushed into a cage formed of plural tongue pieces formed inside of the extension part 33, and a cam part formed in an end of the tongue piece is engaged with a peripheral groove of the eccentric disc, and the carrier 13 is positioned inside of the cutout 51 of the fixing plate 31. After accurately adjusting the sliding door 9 in relation to the horizontal surface, the lock screw 19 is fastened. Structure is thereby miniaturized, and height adjustment is facilitated, and re-adjustment is possible even if the sliding door 9 or a furniture is deflected by the moisture or the like. |
