  When the neck joint is assembled, as shown in FIG. 6A, a communication hole in which the through hole 8 of the head member 1, the through hole 20 of the joint member 4, and the through hole 24 of the neck portion 3 communicate with each other inside the neck joint. 26 is formed, and the elastic body 5 is passed through the communication hole 26. And in the state which adjusted the inclination of the head member 1 with respect to the neck part 3 so that the face part of the head member 1 may face the front, the communicating hole 26 inside a neck joint will be in the state extended linearly up and down, and a communicating hole The elastic body 5 passed through 26 extends vertically without bending.

  Next, when the head member 1 is tilted forward (in the direction of arrow A in FIG. 6A) with respect to the neck portion 3 so that the face portion of the head member 1 faces away from the front, As the tilt increases, the elastic body 5 passed through the communication hole 26 tilts so as to largely fall forward, and at this time, the elastic body 5 tilted so as to tilt forward contacts the front side of the inner surface of the through hole 20 of the joint member 4. Thus, the joint member 4 is rotated forward. Thereby, in a state where the inclination of the head member 1 with respect to the neck portion 3 is adjusted so that the face portion of the head member 1 crawls, the communication hole 26 inside the neck joint is formed in the joint member 4 as shown in FIG. With the rotation, the elastic body 5 is bent forward, and the elastic body 5 passed through the communication hole 26 bends forward at two locations of the upper opening 21 and the lower opening 22 in the through hole 20 of the joint member 4.

  Next, when the head member 1 is tilted backward (in the direction of arrow B in FIG. 6A) with respect to the neck 3 so that the face of the head member 1 faces up from the front, As the inclination increases, the elastic body 5 passed through the communication hole 26 is inclined so as to largely fall backward. At this time, the elastic body 5 inclined so as to fall backward contacts the rear side of the inner surface of the through hole 20 of the joint member 4. The joint member 4 is rotated backward. Thus, in a state in which the inclination of the head member 1 with respect to the neck portion 3 is adjusted so that the face portion of the head member 1 faces upward, as shown in FIG. With the rotation, the elastic body 5 is bent backward, and the elastic body 5 passed through the communication hole 26 bends backward at two locations of the upper opening 21 and the lower opening 22 in the through hole 20 of the joint member 4.

  Further, when the head member 1 is tilted to the left (right) with respect to the neck 3 so that the face of the head member 1 is tilted to the left (right) from the front side, the tilt of the head member 1 increases. The elastic body 5 passed through the communication hole 26 is also tilted so as to fall greatly to the left (right). At this time, the elastic body 5 tilted so as to fall to the left (right) is the through hole 20 of the joint member 4. The joint member 4 is rotated to the left (right) in contact with the left side (right side) of the inner surface. Thereby, in a state where the inclination of the head member 1 with respect to the neck portion 3 is adjusted so that the face portion of the head member 1 is tilted to the left (right), the communication hole 26 inside the neck joint moves to the left as the joint member 4 rotates. The elastic body 5 that is curved (rightward) and passed through the communication hole 26 is leftward (rightward) at two locations of the upper opening 21 and the lower opening 23 in the through hole 20 of the joint member 4. And bend.

  In the neck joint according to the present embodiment, the through hole of the joint member is formed so that the diameter increases from the upper opening toward the lower opening. Even when tilted in the direction, the curvature of the communication hole accompanying the rotation of the joint member can be kept relatively small, and it is not necessary to greatly bend the elastic body passed through the communication hole, and the head member with respect to the neck The elastic force acting on each bent portion of the elastic body when tilting can be reduced. Further, since the joint member is not fixed to any of the head member and the neck of the body member and freely rotates, the degree of bending at both openings of the joint member of the elastic body is automatically adjusted so as not to be biased to either one. The elastic body is evenly bent at both openings of the joint member, and this can also reduce the elastic force acting on each bent portion of the elastic body when the head member is tilted with respect to the neck. .

And the upper part 29 of the notch groove 28 is formed so that a width | variety becomes narrow as it goes to the through-hole 20. As shown in FIG. Further, the upper end portion 30 of the upper portion 29 formed so as to have a narrow width of the notch groove 28 is configured so that the joint member 37 is interposed between the head member 1 and the neck portion 3 of the trunk member 2 as shown in FIG. It is narrower than the width of the elastic body 5 that is passed through the through hole 20 in a state of being positioned so as to be sandwiched. Further, a protrusion 38 is formed at the upper end of the joint member 37 by extending upward the surface facing the surface where the notch groove 28 of the through hole 20 is formed.

  The torso member 2 according to the present embodiment is formed in a hollow shape, and as shown in FIG. 15, a neck 3 is formed so as to extend upward from the chest. And the hollow part (not shown) of the trunk | drum member 2 passes through the neck part 3, and the through-hole 24 opened toward the substantially spherical-shaped upward recessed part 23 formed in the surface facing the head member 1 of this neck part 3. As shown in FIG. It is connected with. Further, the upper end of the neck portion 3 is inclined so as to be lowered from the front side toward the rear side in a side view, and an annular slip stopper 25 is fixed to the upward concave portion 23 of the neck portion 3 so as to surround the opening. In addition, a protrusion 39 extending upward is formed on the front side of the opening. In addition, the protrusion 39 is formed in a shape that fits in a state where play is provided in the lower portion of the notch groove 28 in the joint member 37 in a state where the joint member 37 is fitted in the upward recess 23 of the neck portion 3.

  According to the present embodiment, since the projection 38 that fits into the through hole 8 of the head member 1 is formed on the joint member 37, when the head member 1 is tilted forward with respect to the neck portion 3, (b) of FIG. ), The rear end of the through hole 8 of the head member 1 contacts the projection 38 and pushes the joint member 37 forward, so that the joint member 37 rotates forward only by the catch of the elastic body 5 in the notch groove 28. The elastic body 5 is less likely to be detached from the through hole 20 of the joint member 37 as compared with the case where the above is performed. Further, since the projection 3 that fits into the notch groove 28 of the joint member 37 is formed on the neck portion 3, even if the head member 1 is rotated in the horizontal direction with respect to the neck portion 3, the projection 39 that fits into the notch groove 28. Thus, the joint member 37 is largely prevented from rotating in the horizontal direction, and the opening direction of the notch groove 28 is fixed in one direction. In addition, since the protrusion 39 of the neck part 3 has a shape that fits in a state where play is provided in the lower part of the notch groove 28 in the joint member 37, the head member 1 is tilted in the left-right direction with respect to the neck part 3. Further, the rotation of the joint member 37 in the left-right direction is not hindered.
