  When the lever member 54 is pivoted from the second position to the first position, the position of the lever member 54 needs to be adjusted if the lever member 54 is not at the optimum position with respect to the frame 22. Specifically, first, the lever member 54 is returned to the second position. Then, the shaft member 42 is rotated in the direction in which the screw is loosened, and the position of the lever member 54 is adjusted. Thereafter, the contact portion 58b of the adjustment member 58 is again brought into contact with the outer side surface 22e of the second rear end 22b, and the lever member 54 is pivoted from the second position to the first position. Here, the position of the lever member 54 relative to the frame 22 can be easily adjusted by the adjusting member 58.
