  Of course, the joint member can smoothly rotate as described above, but it is also important that the rotation position can be fixed at an arbitrary position so that the doll toy can take various poses. It has become. In this regard, the techniques disclosed in Patent Documents 1 and 2 are configured such that the rotational position is fixed by frictional resistance during rotation by press-fitting the rotation shaft into the bearing hole.

  However, it is extremely difficult to set the degree of frictional resistance due to various factors during manufacturing, such as mold molding errors, mold wear due to repeated molding, and errors due to resin shrinkage after molding, in the rotational position fixed configuration by frictional resistance. In addition, even if the frictional resistance can be set to an appropriate value, it is difficult to fix at an arbitrary position due to a factor at the time of play that the rotating part is loosened due to wear of the joint member due to repeated joint rotation. Has the problem that it is likely to be impossible.
