PROBLEM TO BE SOLVED: To reduce connection work manhours as compared with conventional manhours. SOLUTION: This connection structure of mutual bar-shaped frame members is provided for connecting an end surface 33b, by butting the bar-shaped other frame member (a horizontal frame member) 33 against a connection side outside surface of bar-shaped one frame member (a vertical frame member) 31. One frame member 31 is provided with a projection part 31f extending in a straight line shape in the longitudinal direction on the connection side outside surface (an outside surface of a connection piece 31e), and the other frame member 33 is provided with a screw receiving part 33a on the inside. Recessed parts 33c and 33c fittable to the projection part 31f of the one frame member 31 is arranged on the butting end surface 33b, and the mutual both frame members are connected and fixed by a screw 18 threadably attached to a screw receiving part 33 of the other frame member 33 by inserting the one frame member 31 in a state of fitting the projection part 31f and the recessed parts 33c and 33c.
