A main frame of a passenger conveyor has a plurality of frame sections divided along the length thereof. Each adjacent pair of frame sections have opposed joint members provided at joint portions of the frame sections. When the frame sections are provisionally assembled, one of the joint members is formed therein with a positioning hole whereas the other joint member is fixedly connected with a positioning pin which, when the frame sections are re-assembled at an installation site, is engaged with the positioning hole to facilitate easy and quick re-assembly of the frame sections. |
