PURPOSE:To prevent disablement of carrying due to deformation of carrying member by providing engaging grooves having downward opening at the opposite sides of carrying rail of hollow cross-section and slidably engaging a chain coupled with holding chips having stopper click in front. CONSTITUTION:A flat board 32 is mounted on the stopper clicks 14 of right and left holding chips 10 while moving a support 30 to the right and left with correspondence to the size of flatboard 32. Then a chain 8 is rotated to travel the holding chip 10 along the sideface 2a of rail 2 thus to carry the flatboard 32. Even if subjected to thermal function in the way of transportation, the heat is radiated through the fins 24 and the radiation is promoted through the hollow section 4, thus to reduce thermal influence. Inclination of the holding chip 10 to the backface side is blocked by a slidable supporting chip 16 to reduce extension/contraction of holding interval as low as possible thus to prevent disablement of carrying. |
