[0117] (Structure of the joint)
[0118] Fig. 2(a) shows a longitudinal cross-sectional view of the joint according to the present invention.
[0119] As shown in FIG. 2(a), the joint 50 is composed of a push rod 52, a main body 51, a steel ball 55, a spring 56 and a copper tube 57.
[0120] (Components of the joint)
[0121] (1)Putter
[0122] The push rod 52 has a protrusion 52a, a first flow path Pi11, and a second flow path Pi12. The protruding portion 52a is provided on the outer periphery of the push rod 52, and has a protruding tapered portion 52b. In addition, the protruding tapered portion 52b is inclined toward the side X2 opposite to the protruding side of the push rod in the push rod longitudinal direction X as it approaches the outer peripheral side. In addition, the protruding taper portion 52b is formed such that the angle formed by the inclination direction of the protruding taper portion 52b and the longitudinal direction X of the push rod is less than or equal to...
