PURPOSE:To freely obtain high speed driving, low speed driving and no driving conditions, by interlocking high and low speed driving rollers to a movable frame with a single motor and operating the movable frame through a selectively operating device. CONSTITUTION:A movable frame 5 is swivellably supported to a mounting base 3 secured to a fixed part of a conveyer frame through a supporting shaft 4, then a high speed pallet driving roller 8 and low speed pallet driving roller 9 are mounted respectively to both upper front and rear ends of said frame 5. Then selection is operated such that tilting of the frame 5 to one side causes a forced contact of the roller 8 to a bottom face of a pallet 1 while tilting reversely to the other side causes a contact of the roller 9 to the bottom face of the pallet 1. Further if the frame 5 is held to a neutral position, the both rollers 8, 9 are not contacted to the bottom face of the pallet, and a no-driving condition can be obtained. |
