PROBLEM TO BE SOLVED: To provide a control lever structure for foldable crane with which housing is facilitated, a structure is simplified and space saving can be made compatible with the degree of freedom in layout. SOLUTION: The main body of lever is divided into two round rods 7 of the same diameter, a slit-shaped recessed part 14 is formed at the lower end of the upper round rod 7 and a planar projecting part 15 to be fitted there is formed at the upper end of the lower round rod so that both the parts can be slid and engaged. Then, a lengthy oblong hole 16 is formed in the axial direction of the projecting part 15 and a pin 17 through the recessed part 14 of the upper round rod 7 is passed through the oblong hole 16 so that both the round rods 7 can not be separated. A cylindrical body 9 fitted outside the engaged recessed part 14 and projecting part 15 at the time of drawing and both the round rods 7 are fixed. At the time of housing, by pulling up the upper round rod 7, the recessed part 14 and the projecting part 15 are disengaged and at the upper end of the oblong hole 16, the upper round rod 7 is bent down with the pin 17 as an axis.
