Abstract
Provided is a long arm supported in a cantilever manner with light weight and high rigidity. The rod 30 is formed from rods 31-33 so as to be a multi-stage telescopic configuration. The rods 32, 33 respectively have upright columns 42, 43 on the tips. The wire 11 is suspended between the tip of the rod 31 and the lead end of the arm via the top of the column 42. The wire 12 is suspended between the base of the column 42 and the lead end of the arm via the top of the column 42. The wire 22 is suspended between the top of the column 42 and the lead end of the arm via the top of the column 43. The tension generation means 50 pulls the wires 10, 20. The air pressure generation means 60 applies pressure to the inside of the rod 30.
