Ａから抜ける恐れが全くないのである。In order to attach the elbow pad 6 to the elbow frame 5, first, the projection 17 projecting from the end surface portion 16 of the elbow pad 6 is fitted into the tip 10A of the upper rod 10 of the elbow frame 5, and the end surface is The tip 16A is covered with the portion 16, the upper rod 10 is received in the groove 20, and the supporting portion 13 is attached to the upper rod 10.
At the same time, the protrusions 18 are engaged with the openings 11, and then the screws 22 inserted from the mounting holes 12 are screwed into the protrusions 18 to make the inclined portion 14 resistant to its elasticity. It is attached by pulling it so that it approaches 9. In this attached state, the inclined portion 14 of the elbow pad 6 is brought into close contact with the upper surface side of the slant rod 9 of the elbow frame 5 by the tightening force of the screw 22, and the mounting portion 13 is attached to the upper rod 10 and the upper surface side of the arc portion. It adheres due to its elastic restoring force. Further, since the slanted portion 14 is in close contact with the slanted rod 9, the rearward movement of the elbow pad 6 is completely regulated, and the protrusion 17 causes the tip 10 of the upper rod 10.
There is no danger of getting out of A.
