PURPOSE:To reduce the manpower required for assembling work thus to reduce the size of movable body or retractable body by feeding/delivering a pallet individually against both supporting/guiding devices through a set of movable body and retractable body. CONSTITUTION:A movable body 24 is moved to engage/disengage the engaging tool 51 or 52 against the portions 53, 54 to be engaged of a pallet 8 thus to advance/retract a retractable body 36. Consequently, the pallet 8 can be fed/ delivered individually against respective support/guide devices 9, 10 to enable reduction of entire size and cost. While since an advance/retract drive is provided on a truck 1, the truck 1 will never interfere with the frame to facilitate wiring while to reduce the manpower required for assembling work and to reduce the size of the movable body 24 or the retractable body. While switching operation of movable body 24 between three positions can be performed reliably through independent operation of cylinders 27, 28. |
