Description

The present invention relates to a joint structure of a doll body.

2. Description of the Related Art Toy dolls are known that are configured by assembling parts for each region and that can be played with various poses. For example, Patent Literature 1 discloses a joint mechanism of a doll toy in which connecting portions such as shoulders are made of a soft material and deformed or bent to widen the movable range.

Registered Utility Model Publication No. 3185443

The design of humanoid robots is known as one of the design themes of doll toys. In doll toys designed as humanoid robots, the main trunks such as the chest, abdomen, and waist are often armored, linear and mechanical designs, and conventionally those trunk parts are a single box-shaped part. has been designed as For this reason, it was easy for the movable parts provided on the trunk to move freely.

Specifically, for example, in TV anime and manga about heroes, poses in which both hands are stretched out in front of the chest and hold a sword or a gun often appear, so the user would definitely want to reproduce that with a doll toy. I hope. However, if the chest is designed as a single box-like body as in the past, the position of the shoulder portion of the upper arm connected to the shoulder joint is almost fixed. For this reason, even if you try to pose the robot with its arms extended forward, only the arms will bend forward while the shoulders remain in the same position, resulting in a so-called "forward pose". Also, there were cases where it was possible to put both hands together by bending the elbow joints with the arms facing forward, but doing so would result in an awkward "stance", far from the original "stance" of extending the arms. Ta. In any case, the wish did not come true.

It is conceivable that the above-described "stance" may be realized by using the joint mechanism using the soft material disclosed in Patent Document 1. However, if the wrinkles and flexures of the soft material become visible, the original attractiveness of the exterior design will be lost, although the "stance" itself is possible. In addition, since the bent soft material tries to restore itself, the above-mentioned "stance" cannot be maintained.

The above-mentioned "stance" problem is just an example, and it is a problem that occurs in other joints when the joints are greatly (or deeply) bent.

[First Embodiment]
FIG. 1 is a perspective external view of the upper body portion of the doll toy in the first embodiment.
The toy doll 2 is a toy configured by assembling parts for each part. In the illustrated example, the head 10, the chest 20, the abdomen 30, the upper arms 40, and the backpack 50 of the toy doll 2 are selectively illustrated. Parts (for example, lower arms, waist, legs, etc.) are also provided as appropriate. The user can arbitrarily change the relative orientations and relative postures of these parts, and enjoy changing the poses of the toy doll 2 in various ways.

The chest 20 of this embodiment has a central chest part 22 , a left chest part 24 and a right chest part 26 .
Physically, the central chest part 22 is the first part that constitutes the trunk, and forms the left and right central portions of the chest 20 in this embodiment. The left chest part 24 and the right chest part 26 are third parts that constitute part of the trunk or the appearance of the trunk. In this embodiment, they form a right half corresponding to the right shoulder and right lung, and a left half corresponding to the left shoulder and left lung. The outer surface of the central chest part 22, the outer surface of the left chest part 24, and the outer surface of the right chest part 26 form an integrally connected appearance as the chest 20. - 特許庁

FIG. 2 is a front view of the doll toy 2 in this embodiment, including a partial cross-sectional view of the front side of the left chest part 24 .
FIG. 3 is a front exploded view of the doll toy 2 in this embodiment, including a partial cross-sectional view of the left chest part 24 cut from the front side.
FIG. 4 is a top view of the doll toy 2 of this embodiment.

As shown in FIG. 3, the central chest part 22 of this embodiment is symmetrical and has an upper part 221 and a lower part 222 .
The upper part 221 is a substantially box-shaped body with left, right, and bottom openings, and forms the upper surface, central front surface, and central rear surface of the chest 20 . The upper portion has a joint portion 223 for connecting the ball joint 12 that connects the head portion 10 .
The lower part 222 includes a bottom surface 224 of the chest 20 that is connected to the abdomen 30, a joint connection column portion 225 that connects to the joint portion 223, a left swing shaft 226 that connects the left chest part 24 so that it can rotate left and right, and a right swing shaft 227 that pivotally supports the right chest part 26 so as to rotate left and right.

The left chest part 24 and the right chest part 26 are symmetrical to each other in this embodiment. Hereinafter, the left chest part 24 will be described as a representative.
The left chest part 24 is a box-shaped body that is open to the right and downward, and has a left exterior part 241 that forms the front, side, back and top surfaces of the left half of the chest, and a left swing shaft 226. and a left arm ball stud 243 for ball joint connection of the left upper arm 40 (second part). The left arm ball stud 243 forms the front-rear center upper surface of the left half of the chest and is pivotally supported by a left shoulder shaft 244 extending in the front-rear direction inside the left armor part 241 so as to be able to swing up and down. In other words, the toy doll 2 can be made to take a pose in which the left shoulder is raised by vertically swinging the left arm ball stud 243 with the left shoulder shaft 244 .

In this embodiment, the movable shaft (left arm ball stud 243, left shoulder shaft 244) for changing the angle of the upper arm 40 (second part) changes the orientation of the left chest part 24 (third part). It is provided at a position farther from the center line L1 of the trunk than the movable shaft (left swing shaft 226) for moving (see FIG. 3). When viewed from above, the left swing shaft 226 is erected at a position close to the rear surface of the chest with respect to the front-rear center line L2 of the chest 20 (see FIG. 4).

As shown in FIG. 3, in the upper body of the doll toy 2 of this embodiment, the left chest part 24 is assembled to the lower part 222 from above by inserting the left swing shaft 226 into the left bearing 242. It is Similarly, the right chest part 26 is attached to the lower part 222 from above by inserting the right swing shaft 227 into the right bearing. Furthermore, an upper part 221 is assembled from above the left chest part 24 and the right chest part 26 . The upper arms 40 are attached to the left chest part 24 and the right chest part 26 respectively, and the head 10 is attached to the joint part 223 .
Therefore, as shown in FIG. 4, the tip of the right end of the left chest part 24 is inserted into the left opening of the central chest part 22, and the tip of the left end of the right chest part 26 is inserted. is inserted from the right opening of the central chest part 22 into the inside thereof.

FIG. 5 is a cross-sectional view taken along line AA of FIG. 2, and is a cross-sectional view when both shoulders are turned rearward. As shown in FIG. 5, the toy doll 2 of this embodiment can be made to take a pose in which both shoulders are bent backward and the chest is puffed out.
That is, the direction of the left chest part 24 is changed around the left swing shaft 226 so that the angle between the rear surface of the central chest part 22 and the rear surface of the left chest part 24, which constitute the trunk, is reduced. can be done. As a result, the left arm ball stud 243 rotates backward, and the front of the chest 20 is deformed so as to be curved forward to form a convex shape, and a pose as if the chest is puffed out is completed.

At this time, the end of the left chest part 24 on the front side and near the center chest part 22 is pulled out as the part inserted inside the center chest part 22 is pulled out as the direction is changed, and the left chest part 24 and the center are pulled out. It is made difficult to create a gap between the chest parts 22.例文帳に追加As a result, the continuous appearance of the chest 20 is favorably maintained. The same is true between the right chest part 26 and the central chest part 22 .

Also, the end of the left chest part 24 near the center chest part 22 and the end of the right chest part 26 near the center of the chest are provided with tapered surfaces T, respectively. It avoids contact with the central chest part 22 and creates a smooth connection of the outer surface when changing the direction. The shape of the tapered surface T is not limited to a straight inclined surface, and may be formed by a curved surface composed of a rotating body centered on the swing shafts 226 and 227, and contact with the central chest part 22 may be avoided. It may be formed with a free-form surface whose volume is reduced so as to reduce the volume.

FIG. 6 is a cross-sectional view taken along line AA of FIG. 2, and is a cross-sectional view when both shoulders are turned forward. As shown in FIG. 6, the toy doll 2 in this embodiment can be made to take a pose in which both shoulders are shrugged forward.
That is, change the orientation of the left chest part 24 around the left swing shaft 226 so that the angle between the front surface of the central chest part 22 and the front surface of the left chest part 24, which constitute the trunk, is reduced. can be done. As a result, the left arm ball stud 243 rotates forward, deforming the front of the chest 20 so that the width in the left-right direction becomes narrower, and a pose as if the shoulders are shrugged forward is completed. At this time, the end portion of the left chest part 24 closer to the front central chest part 22 is inserted further inside the central chest part 22 as the orientation is changed. This reduces the volume of the front chest formed by the left chest part 24 and the central chest part 22 when trying to make a pose as if the shoulders are shrugging forward, so that the movement of the upper arm 40 is not hindered. By doing so, it is possible to preferably maintain the continuous appearance of the chest 20 while expanding the movable range of the upper arm 40 . The same is true between the right chest part 26 and the central chest part 22 .

By being able to take poses in which both shoulders are shrugged forward, the toy doll 2 in this embodiment can be made to take more diverse and natural poses.
Specifically, for example, as shown in FIG. 7, if the chest 20 is formed in a box shape like a conventional doll toy (center chest part 22, left chest part 24, right chest part 26), the shoulders cannot be shrugged forward, so even if both arms are directed forward (lower side in FIG. I can only do posture.

However, as shown in FIG. 8, if the chest 20 is divided into a central chest part 22, a left chest part 24, and a right chest part 26 as in this embodiment, the shoulders can be shrunk forward. With both arms facing forward, it is possible to pose as if both arms are stretched out and crossed in front of the chest. For example, you will be able to reproduce cool poses such as holding a gun in front of you.

Moreover, the movable shafts (left swing shaft 226, right swing shaft 227) of the left chest part 24 and the right chest part 26 are aligned with the ball stud 243, which is the movable shaft of the left and right arms, and the center of the trunk (center line L1). ) (see FIG. 3), the central chest part 22, the left chest part 24, and the right chest part 26 are arranged in a row as a chest, and a top view of the impression can be realized.

Further, the left swing shaft 226 and the right swing shaft 227 are provided at a position close to the back with respect to the center line L2 in the front-rear direction of the chest 20 (see FIG. 4). By increasing the turning radius of the ends of the left chest part 24 and the right chest part 26 near the central chest part 22, the tapered surface for avoiding interference with the central chest part 22 is reduced, The center chest part 22, the left chest part 24, and the right chest part 26 contribute to realizing a top view of the impression that the chest is connected.

[Second embodiment]
Next, a second embodiment to which the present invention is applied will be described. In the following description, differences from the first embodiment will be mainly described, and the same reference numerals will be assigned to the same components as in the first embodiment, and duplicate descriptions will be omitted as appropriate.

FIG. 9 is a front view of the upper body showing a configuration example of the toy doll 2B in this embodiment.
FIG. 10 is a partial cross-sectional front view showing an example of the internal structure of the toy doll 2B.
FIG. 11 is a left side view of the toy doll 2B.

The chest 20 of the toy doll 2B is divided into a central chest part 22B, a left chest part 24B, and a right chest part 26B. The central chest part 22B is a substantially box-shaped body that opens to the left and right, and the upper part 221B and the lower part 222B are connected. The left chest part 24B and the right chest part 26B are substantially bowl-shaped or substantially dish-shaped structures that cover the left and right openings of the central chest part 22B, respectively. That is, the right end of the left chest part 24B covers the outside of the left opening of the central chest part 22B, and the left end of the right chest part 26B covers the outside of the right opening of the central chest part 22B. It constitutes an integrated and continuous appearance as

The connection between the central chest part 22B and the left chest part 24B and the right chest part 26B is achieved by ball joints 27 in this embodiment. Also, the connection between the upper arm 40 and the left chest part 24B and the right chest part 26B is realized by a ball joint 28 in this embodiment. In other words, the degree of freedom of the shoulders and arms of the toy doll 2B of this embodiment is higher than that of the first embodiment.

Of course, the toy doll 2B of this embodiment can also be made to take a pose in which both shoulders are shrugged forward as in the first embodiment, and effects similar to those of the first embodiment can be obtained.
That is, assuming that the chest 20B is formed in a single box shape (assuming that the central chest part 22B, the left chest part 24B, and the right chest part 26B are not divided and integrated). ), as shown in FIG. 12, since both shoulders cannot be shrunk forward, even if both arms are directed forward (lower side in FIG. 12), only a so-called "mimic the forward posture" is possible.

However, as shown in FIG. 13, the chest 20B is divided into a central chest part 22B, a left chest part 24B, and a right chest part 26B. If you turn it, you can pose as if you stretched your arms out in front of your chest and crossed them. For example, you will be able to reproduce cool poses such as holding a sword in front of your chest.

In addition, in this embodiment, the connection between the central chest part 22B, the left chest part 24B and the right chest part 26B is realized by the ball joint 27, so that the shoulders can be moved not only forward but also diagonally forward and downward. , obliquely forward, overhead, obliquely upward rearward, and obliquely downward rearward. The outer surface of the central chest part 22, the outer surface of the left chest part 24, and the outer surface of the right chest part 26 form an integrally connected appearance as the chest 20. - 特許庁

[Third Embodiment]
Next, a third embodiment to which the present invention is applied will be described. In the following, the differences from the first and second embodiments will be mainly described, and the same reference numerals will be assigned to the same components as in the first and second embodiments, and redundant description will be omitted as appropriate. do.

FIG. 14 is a front view showing a configuration example of a toy doll 2C according to this embodiment.
The toy doll 2C has a head 10, a chest 20, an abdomen 30, and a waist 60 in order from the top, and adjacent parts among these are connected by ball joints so that the relative angle can be changed.

The waist portion 60 includes a waist base portion 70 and a plurality of exterior portions 80 covering side surfaces of the waist base portion 70 .

The exterior part 80 includes a large droop part 81 that integrally covers the front of the waist part 60 from the navel to the crotch area, and a left front droop that is connected to the upper end of the large droop part 81 by a ball joint and covers the front of the left and right thigh joints. A portion 83 and a right front hanging portion 84, a left hanging portion 85 and a right hanging portion 86 covering the left and right side surfaces of the waist portion 60, and a tail hanging portion 87 covering the rear side of the waist portion 60 (see FIG. 17). The left hanging portion 85 and the right hanging portion 86 are supported at their upper ends so as to be swingable about the horizontal axis in the front-rear direction with respect to the waist base portion 70, and are connected at their lower ends so as to be swingable vertically.

FIG. 15 is a perspective exploded view showing an example of the connection structure of the waist base 70, the thigh 44, and the droop 81. As shown in FIG. In order to facilitate understanding, a part is shown transparently, and the connection structure between the waist base 70 and the other hanging parts (left hanging part 85, right hanging part 86, buttock hanging part 87) is omitted. there is

The waist base 70 has a substantially box shape elongated in the front-rear direction and the up-down direction, and has a ball stud 71 at its upper end for connecting with the abdomen 30 by a ball joint.
Also, a large drape link 72 is connected to the front upper portion of the waist base 70 so as to be vertically swingable. The rear joint of the obatare link 72 is connected to the waist base 70 by a link movable shaft 73 so as to be able to swing up and down. In addition, the front joint of the large hanging link 72 is connected by the large hanging shaft 74 at the bearing portion 82 provided in the upper and lower middle part of the back surface of the large hanging portion 81, so that the large hanging portion 81 can swing up and down. Support.

Thigh links 76 having ball studs 75 for connecting with the thighs 44 by ball joints are connected to the left and right side surfaces of the waist base 70 .
A front joint of the thigh link 76 is connected to the link movable shaft 73 . A rear joint of the thigh link 76 is fitted in an arc-shaped guide groove 77 provided in the waist base 70 . That is, the thigh link 76 can swing the rear joint portion up and down around the link movable shaft 73 along the guide grooves 77 on the left and right side surfaces of the waist base portion 70 .

In addition, when viewed from the front, the movable shaft (ball stud 75) for changing the angle of the thigh 44 (second part) with respect to the abdomen 30 (first part) is attached to the large droop portion 81 (third part). It is configured to be provided below the movable shaft (Odare movable shaft 74) for changing the direction of the . In addition, when viewed from above, the movable shaft (ball stud 75) for changing the angle of the thigh 44 is located behind the movable shaft (large droop movable shaft 74) for changing the orientation of the droop portion 81. , and is provided at a front-rear position closer to the center of the trunk (ball stud 71).

Next, with reference to FIGS. 16 to 19, the possible positional relationships of the parts around the waist 60 when the toy doll 2C is changed from the upright posture to the standing knees and forward bending posture will be described. It should be noted that in these figures, some of the parts are shown in a see-through manner to facilitate understanding of the relative positional relationship, and some of the parts are omitted from the illustration.

FIG. 16 is a simplified cross-sectional view showing the positional relationship of the parts around the waist 60 when the toy doll 2C is in an upright position.
The abdominal portion 30 has a socket portion 31 that connects with the ball stud 71 in the internal space, and an opening portion 32 into which the upper end of the large hanging portion 81 can be inserted at the front lower end. However, in the upright posture, the large drooping portion 81 is almost in an upright posture, and its upper end is positioned close to the front surface of the abdomen 30 to cover the opening 32 . Therefore, when the toy doll 2C is viewed from the front, the presence of the opening 32 is inconspicuous, and the chest 20→abdomen 30→waist 60 forms an appearance without a large break. In addition, in the upright posture, the lateral circumference of the waist portion 60 is also formed by the exterior portion 80 to form a large continuous appearance without a break (see FIG. 14).

From here, in order to make the toy doll 2C stand and kneel, it is necessary to turn the thighs 44 (shown in perspective in FIGS. 16 to 19) forward, and the parts around the waist 60 transitions in the order of FIG. 17→FIG. 18→FIG. That is, the thigh link 76 is swung around the link movable shaft 73 as a rotation axis, and the ball stud 75 is lowered to the front lower end portion of the waist base portion 70 . At the same time, the thighs 44 are laid down with their front surfaces facing upward.

In order to make the doll toy 2C bend forward, the angle formed by the abdominal portion 30 with respect to the waist portion 60 is adjusted while changing the angle of the droop portion 81 in parallel with changing the directions of the thigh link 76 and the thigh portion 44. Turn to reduce. That is, the abdomen 30 is tilted forward.

Specifically, as shown in FIG. 16 , the front joint is above the link movable shaft 73 and the ball stud 75 in the upright posture of the obatare link 72 . To bend forward from this point, first, as shown in FIGS. 17 to 18 , the Odare link 72 is rotated about the link movable shaft 73 so as to lower the front joint. Then, the swinging axis of the drooping link 72 is lowered and moved forward, and the swinging shaft of the drooping section 81 is separated from the abdomen 30 . As a result, the interference prevention space Sp (see FIG. 18) between the abdomen 30 (first part) and the oval part 81 (third part) is enlarged.

From there, as shown in FIGS. 18 to 19 , the upper end of the drooping portion 81 is inclined toward the opening 32 of the abdomen 30 . In addition, the abdomen 30 is tilted forward to insert the upper end of the great droop portion 81 into the internal space of the abdomen 30 . As a result, while the abdomen 30 is greatly bent forward, the appearance from the abdomen 30 to the waist 60 can be formed without a large discontinuity when viewed from the front. A tapered surface T is provided at the upper end of the drooping portion 81 (see FIGS. 15 and 16) to avoid contact with the opening 32 of the abdomen 30 when the direction of the drooping portion 81 is changed. produce an effect.

Further, the movement of the swinging position and the change of the direction of the droop portion 81 have the effect of shaping the lateral appearance of the waist portion 60 into a continuous appearance without a large break.
20 and 21 are simplified perspective views showing the parts around the waist 60. FIG.
Assuming that the oscillating position of the abductor portion 81 (the front joint of the abendor link 72; the abendor movable shaft 74 (see FIG. 15)) cannot be changed as in the present embodiment, as shown in FIG. In addition, when the right thigh 44 is swung forward to make the doll toy 2C stand and kneel, the right front hanging part 84 is also swung up, but the large hanging part 81 is in an upright posture. It remains in position and produces a large visible discontinuity 9 in the right groin. However, in the present embodiment, as shown in FIG. 21 , the drooping portion 81 can be swung forward and laid down, so that there is a large gap in the lateral circumference of the right drooping portion 84→the drooping portion 81→the left drooping portion 83. It is possible to form an appearance that does not have any shape, and to improve the design of the appearance.

According to the joint structure of the doll toy according to the embodiment described above, the second part (for example, the upper arm 40 in FIG. 8, the thigh 44 in FIG. 14) is replaced with the first part (for example, the chest in FIG. 20, abdomen 30 in FIG. 14) when moving the third part (e.g., left chest part 24 and right chest part 26 of chest 20 in FIG. 8, FIGS. 14 and 21). The large droop portion 81, the left front droop portion 83, and the right front droop portion 84) can be moved in accordance with the movement of the second part. For example, if the first part is the central chest, the second part is the arms, and the third part is the left and right chests, and the doll toy is made to pose with its arms folded in front of its chest, the arm movements Together, the left and right chests (left and right parts of the chest) can be moved. In other words, the trunk (the whole chest in this example), which was conventionally configured as a single box, is divided into the first part and the third part, and the third part moves along with the movement of the second part. By making it movable, the degree of freedom of movement of the joint can be increased. In addition, visually, the 3rd part mediates between the 1st part and the 2nd part, so there is a sense of discontinuity (a large gap in appearance) that connects the 1st part to the 3rd part to the 2nd part. Since it is possible to form a non-continuous appearance, it is possible to suppress the reduction in the attractiveness of the appearance design.

In addition, in the present embodiment, the first part and the third part partially overlap with one outside and the other inside when the third part rotates in the direction to reduce the angle formed. With such a configuration, it is possible to avoid interference between the first part and the third part, and form a continuous appearance with less visual discontinuity.

Further, in the present embodiment, the third part has a tapered surface at the end near the first part for avoiding contact with the first part during rotation. Even if the gap between the part and the third part is made small, it is possible to reliably avoid interference between the two parts. In addition, the tapered surface appropriately buffers the difference in angle between the outer surface of the first part and the outer surface of the third part, and even if the first part and the third part have a linear design, the appearance of both parts is continuous. can appear smoother.

In addition, in the present embodiment, the movable shaft for changing the angle of the second part (for example, the left arm ball stud 243 and the left shoulder shaft 244 in FIG. 3) changes the direction of the third part when viewed from above. The second part is arranged on the side of the first part because it is provided at a position farther from the center of the trunk than the movable shaft (for example, the left swing shaft 226 in FIG. 3) for Even with this configuration, a third part that forms an angle with the first part at a gentler angle than the angle that the second part forms with the first part can be arranged between the first part and the second part. Therefore, when the pose of the doll toy as a whole is seen, the outer surface of the first part, the outer surface of the third part, and the outer surface of the second part are connected, so that the angle change of the outer surface becomes smoother and looks beautiful.

Further, in the present embodiment, the first parts are parts for the center of the chest, the second parts are parts for arms, and the third parts are parts located on the left and right sides of the chest. , By dividing the chest into at least three parts, the center and left and right, it is possible to shrug the shoulders forward, and with both arms stretched out in front of the chest, both hands are folded to hold a sword or gun. You will be able to reproduce cool poses with doll toys.

Further, in the present embodiment, the third part has a support portion that supports the second part, so that the third part can also serve as a support structure for the second part.

In addition, in the present embodiment, in a front view, the movable shaft for rotating the second part (for example, the ball stud 75 in FIGS. 14 and 15) is the movable shaft for rotating the third part. Since it is configured to be provided below the shaft (for example, the Odare movable shaft 74 in FIG. 15), even in a configuration in which the second part is arranged below the first part, the second part is the first part. A third part can be positioned between the first and second parts that forms an angle with the first part that is less steep than the angle it forms with the parts. Therefore, when the pose of the doll toy as a whole is seen, the angle change of the outer surface connecting the outer surface of the first part, the outer surface of the third part, and the outer surface of the second part becomes smoother, and the doll looks beautiful.

In addition, in the present embodiment, the third part has a portion above and a portion below the movable shaft for rotating the third part (for example, the large vertical movable shaft 74 in FIG. 15). , when the third part rotates in the direction to reduce the angle formed, one of the upper portion and the lower portion of the third part moves outward from the first part, and the other moves to the outside of the first part. Since it is configured to partially overlap the inside of the first part (for example, FIGS. 16 to 19), interference between the first part and the third part is avoided, and there is little sense of discontinuity and continuity in appearance. can form a certain appearance.

Further, in the present embodiment, the first part is an abdominal part (eg, abdomen 30 in FIG. 14), and the second part is a leg part (eg, thigh 44 in FIG. 14). , and the third part is a part for appearance of the waist (for example, the large hanging part 81 in FIG. 14). It is possible to change the position of the waist appearance part. Therefore, for example, the appearance parts around the waist can be changed to appropriate positions according to the standing knee pose, and a natural and good-looking appearance can be realized.

Further, in the present embodiment, the third part is configured to swing with respect to the first part, one end supports the swing shaft of the third part, and the other end is pivotally supported. A link part (for example, an obatare link 72 in FIG. 15) is further provided, and the swing axis of the third part is vertically positioned by swinging the link part vertically around the other end. Since it is configured to be adjustable, it is possible to change the position of the swing axis of the third part (for example, the droop portion 81 in FIG. 14). Therefore, it is possible to expand the changeable postures and positions of the third part and contribute to realizing various poses of the toy doll.

Further, in this embodiment, when the second part is rotated so as to reduce the angle formed, the link part is swung downward to prevent interference between the first part and the third part. Since it is configured so that the space can be expanded, when the link part swings downward as the second part rotates, the entire third part moves away from the first part to prevent interference. Space expands. The expansion of the interference prevention space is an expansion of the room for changing the third part to a position where it does not interfere with the first part, and makes it easier to change the orientation of the third part in a direction that reduces the angle formed with the first part. Become. As a result, the angle formed by the third part with respect to the first part can be made smaller in terms of the doll toy as a whole.
