PURPOSE:To make the opening/closing operation of a sliding door smooth by providing a rail means in which a first wall face part and a reversely directed second wall face part are erected on a horizontal part, while installing a pair of roller means which rollably hold the horizontal part of said rail means in between on said sliding door. CONSTITUTION:A guide rail 32 is fixed to the inside of the lower panel 20 of a sprash guard via a bracket 30. And, a horizontal part 36 which exists between wall face parts 38, 34 are interposedly held by a pair of rollers 42, 46 which are installed on a sliding door 14. Thereby, even if the sliding door 14 is moved in the Y direction, either the roller 42 is brought into contact with the wall face part 34 or the roller 46 with the wall face part 38, without causing the delailment of the rollers 42, 46 off of the rail 32. Also, even if chips or machining liquid resulting from the machining of a workpiece may fall on the guide rail 32, these fall along the outer face of the wall face part 38 from the horizontal face part 36. Due to such a structure, the opening/closing operation of the sliding door 14 of the sprash guard can be smoothly carried out. |
