In order to increase the bending angle of the joint, it is necessary to deepen the notch of the inverted U-shaped side part located on the bending direction side at the other side joint part. When the joint is extended, when the joint is extended, a large dent is formed on the side of the joint in the bending direction and the appearance is deteriorated. It was.

  On the other hand, in the joint structure of the doll disclosed in Patent Document 2, the upper knee fitting recess formed at the lower end of the member constituting the thigh of the doll is formed at the upper part of the member constituting the joint of the doll. The lower knee fitting convexity formed on the lower part of the member constituting the joint of the doll is fitted to the upper knee fitting convex part and the lower knee fitting concave part formed on the upper end part of the member constituting the lower leg of the doll Since the joint is bent, the joint has two fulcrum points, and the joint can be bent at a deep angle, but the two joint lines are on the extension direction side of the joint that the viewer in contact with the doll observes most carefully. If each member is formed so that only one joining line appears, a large gap is generated at the joining position of each member when the joint is bent.

  Therefore, the present invention has as a technical problem to provide a joint structure of a doll that has a beautiful appearance in the extended / bent state of the joint and can narrow a gap generated between each member when the joint is bent. As a result of repeating trial manufacture and experiment in order to realize the embodiment, a pair of exterior members formed in a hollow shape and a joint member formed in a hollow shape positioned between both exterior members are formed in the hollow portion of each member. In the joint structure of a doll that is connected to bendable by being pulled by an elastic body that has been passed through, the exterior surface located on the bending direction side of the joint at the distal end portion of any one of the exterior members reaches the distal end. The interference mitigation piece is extended from the joint member so as to close the notch formed at the tip of one of the exterior members, and the joint must not bend more than a predetermined angle. In the state, the surface of the interference mitigation piece becomes a part of the exterior surface at the distal end portion of one exterior member, and the exterior is located on the bending direction side of the joint at the distal end portion of the other exterior member when the joint is bent at a predetermined angle or more. The surface interferes with the interference mitigating piece and the surface of the interference mitigating piece sinks inward of one of the exterior members, so that a recess is formed in the notch and the joint bends at the tip of the other exterior member in the recess. If the exterior surface located on the direction side is fitted, the gap between the members can be narrowed when the joint is bent and extended, and the technical problem is solved. Achieved.

  The technical problem can be solved by the present invention as follows.

  That is, in the joint structure of a doll according to the present invention, a pair of exterior members formed in a hollow shape and a joint member formed in a hollow shape positioned between both exterior members are passed through the hollow portion of each member. It is a joint structure of a doll connected so as to be bent by being pulled by each other by an elastic body, and the exterior surface located on the bending direction side of the joint at the distal end portion of any one of the exterior members reaches the distal end A notch formed by notching is formed, and the interference mitigation piece extends from the joint member so as to block the notch formed at the tip of one of the exterior members, and interference occurs when the joint is not bent more than a predetermined angle. The surface of the relaxation piece is a part of the exterior surface at the distal end of one exterior member, and the joint is bent at the distal end of the other exterior member when the joint is bent at a predetermined angle or more. When the exterior surface located interferes with the interference mitigating piece and the surface of the interference mitigating piece sinks inward of one of the exterior members, a recess is formed in the notch, and the recess is formed at the tip of the other exterior member. The exterior surface located on the bending direction side of the joint is fitted.

  Further, according to the present invention, in the joint structure of the doll, the interference mitigation piece fitted in the notch is detachably engaged with the notch.

  Further, a doll according to the present invention has any one of the joint structures described above.

  According to the present invention, the interference mitigation piece is extended from the joint member so as to block the notch formed at the distal end portion of the one exterior member, and the interference mitigation piece does not cause the joint to bend more than a predetermined angle. Since it becomes a part of the exterior surface at the tip of the member and sinks into the inside of one of the exterior members in a state where the joint is bent at a predetermined angle or more, when the bending angle of the joint is deepened, The depression that is inevitably formed on the bending direction side can be opened and closed as necessary by swinging the interference mitigating piece, so that a beautiful appearance is maintained in both the extended and bent states of the joint.

  Therefore, it can be said that the industrial applicability of the present invention is very high.
