PROBLEM TO BE SOLVED: To provide a mounting structure of a supporting rod, in which a mounting strength is increased for the lower end of the supporting rod and in which an option member is made stably attachable to the supporting rod. SOLUTION: In the lower end of a supporting rod 7, there is fixed a supporting rod mounting member 17 equipped with a downward mounting piece 17b that extends downward from the lower end of the supporting rod 7 and which made a front/rear dimension larger than that of the supporting rod 7. The upper end in front/rear both ends of the downward mounting piece 17b is brought in contact with or brought close to the lower face of the opposing part of a front/rear top plate 5, and in this state, the downward mounting piece 17b is fixed to the inner side face of a leg 2.
