3 can be maintained. In addition, the torso 38 can be bent in accordance with the torsion of the support member 40 and the upper body 23.

As described above, when the doll body 21 is made of a flexible soft material for its constituent members, for example, the outer shells of the body, legs, arms, etc., when the members are turned, However, even if they come into contact with each other, they bend, so that the rotation angle can be increased. Further, a press-contact member 2 made of rubber or the like is attached to a movable portion (for example, the flange 68 or the spherical joint 48) of a joint that connects each member.
When the 4, 49 are pressed against each other, the movable portion can move when an appropriate force is applied, and the position is maintained when no force is applied.

[0042]

As described above, the first aspect of the present invention is as follows.
The described joint device includes a first member and a second member, and one spherical joint of the first member is rotatably held by the one holding portion of the second member. The first member can be rotated and bent with respect to the second member, and the other spherical joint is pressed into the other holding portion of the second member of the other joint device to form another member. There is an effect that it can be connected to the joint device. In addition, since the flange is provided on the outer peripheral surface of the second member, there is an effect that the second member can be attached to another member without being pulled out by using the flange.

In the joint device according to the second aspect of the present invention, in addition to the above-described effects, since the locking projection is formed on the flange, it is possible to use the joint projection so as to be non-rotatably attached to another member. .

In the doll body according to the third aspect of the present invention, the lower body part and the upper body part are connected by a supporting member, and the supporting member is composed of the joint device and the second member. There is an effect that it can move like a spine, can bend or twist the upper body, and can maintain the bent or twisted state.

In the doll body according to the fourth aspect of the present invention, in addition to the above-described effects, the flange of the second member at one end of the supporting member is engaged with the engagement groove formed in the mounting portion of the lower body portion. Since the flange of the second member at the other end of the supporting member is engaged with the engaging groove formed in the mounting portion, the effect that the supporting member is unlikely to come off from the lower body portion and the upper body portion is obtained. is there.
Further, when a plurality of engagement grooves are formed in the mounting portion, there is an effect that the height can be adjusted by the engagement grooves with which the flanges are engaged.

In the doll body according to the fifth aspect of the present invention, in addition to the above-described effects, a lower body part is provided with a trunk part which covers the skeletal member and is inserted into the upper body part, and the trunk part is formed of a soft synthetic resin. Therefore, even if the upper body is bent, twisted, or stretched, the skeletal member does not appear to the outside and can be flexed as it moves.

In the doll body according to the sixth aspect of the present invention, in addition to the above-described effects, since the body is filled with a flexible material, the doll body can be flexed naturally like a human abdomen.
