PROBLEM TO BE SOLVED: To easily and surely position a conveyor by comprising a means for laterally moving a conveyor to a base through the engagement of screw, and mounting a handle for rotating the screw on an upper part of the conveyor frame. SOLUTION: A pair of front and back horizontal shafts 3, 3 extended in the axial direction of a conveyor are mounted on a conveyor frame 1 through a bracket 2, and each horizontal shaft 3 is supported axially slidably by a bearing mounted on a base 6. Whereby the conveyor frame 1 is supported on the base 6 movably in the width direction. A vertical shaft 8 is supported on the frame 1 through a bearing 7, a threaded rod 10 is mounted at a lower side of the frame 1 in parallel with the horizontal shaft 3 through a bearing 9, and a nut 13 mounted on the base 6 is engaged with the threaded rod 10. By turning a handle 12 mounted on an upper end of the vertical shaft 8, the threaded rod 10 is rotated through a bevel gear array 11, whereby the conveyor frame 1 is laterally moved to the base 6.
