CONSTITUTION: A spider connecting part(1) for connecting two shaft bodies(2,3) to move easily is composed of a spider(4) arranged between two shaft bodies and composed of four shaft parts(41A), outer races(8A,8B,8C,8D) rotated and arranged in four shaft parts and combined with the shaft bodies, and an attaching part formed in the outer race and composed of a balance weight(16) to keep the balance with the outer race. A screw hole(17) is formed in the attaching part to insert the balance weight, and a key part(10) is formed in the outer race corresponding to a key groove(14) in the end of the shaft body.
