PURPOSE:To prevent abrasion dust produced by slides between a plurality of parts from getting into the side of a film by providing oilless sliding members on sliding surfaces of a clip mount body and a rail both of a tenter frame and providing a rail cover with its margin inserted into a groove formed in the clip mount body. CONSTITUTION:A clip 1 mounted on a clip mount 3 holds a film 11 with a lever 6 and a liner 7 sandwiching it therebetween. Oilless sliding plates 21a, 22a, and 23a are mounted on surfaces on which the clip mount 3 slides in a rail 2. A groove 72 is formed in a clip mount body 30 and a rail cover 71 is fixed to the rail 2 and the body 30 by cap nuts 44 with the margin of the cover 71 inserted into the groove 72, preventing abrasion dust from going out into the side of the film 11. Further, a cavity 80 is formed in the inner bottom of the rail 2 on the opposite side to the film 11 with respect to the clip mount 3 and the cavity 80 receives and stores the abrasion dust. The cavity 80 has a through hole 64 for discharging the abrasion dust therethrough. |
