[0009] Hereinafter, the embodiments will be described in detail with reference to the accompanying drawings. Note that the following embodiments do not limit the scope of the invention as claimed, and not all combinations of features described in the embodiments are necessarily essential to the invention. Two or more of the features described in the embodiments may be arbitrarily combined. Furthermore, the same reference numerals are used for the same or similar components, and redundant explanations will be omitted.

[0010] (1. Overall structure of the doll body) 1 shows the overall configuration of a doll body 1 according to an embodiment. The doll body 1 comprises a head part 11, a torso part 12, a waist part 13, leg parts 14, and arm parts 15 as part parts representing individual parts. These parts 11 to 15 may be collectively referred to as part parts. For example, the leg part 14 is provided rotatably relative to the waist part 13, and the arm part 15 is provided rotatably relative to the torso part 12.

[0011] The above-described body part parts 11 to 15 may be further divided. As will be described in detail later, leg part 14 includes knee part 141, thigh part 142, lower leg part 143, and foot part 144. Arm part 15 includes elbow part 151, upper arm part 152, forearm part 153, and hand part 154. While Fig. 1 shows leg part 14 and arm part 15 on the left side, the same applies to the right side.

[0012] In this specification, when explaining the positional relationship of each part, terms such as front (forward), back (rear), left (left side), right (right side), up (upper), down (lower), inside (inside), and outside (outside) may be used, but these terms are relative to the doll body 1. For example, the front corresponds to the front side of the doll body 1, and the back corresponds to the back side of the doll body 1.

[0013] Each of the above-mentioned body part parts 11 to 15 (including parts 141 to 144, 151 to 154) can be configured by interconnecting one or more parts (component parts). For example, the leg part 14 (parts 141 to 144) is configured by directly / indirectly connecting multiple component parts, more specifically, by connecting two adjacent component parts fixedly or rotatably (or swingably). Similarly, for example, the arm part 15 (parts 151 to 154) is configured by directly / indirectly connecting multiple component parts.

[0014] The concept of connection between parts can include various connection modes, such as attaching, connecting, or fixing one part to another. For ease of understanding, expressions consistent with the embodiments will be used in this specification, but the present invention is not strictly limited to those expressions (the expressions can be replaced with similar expressions). The same applies to other expressions.

[0015] In this specification, the individual components of the doll body 1 are referred to as "parts," but the concept of parts refers not only to the smallest units that can be disassembled by the user, but also to combinations of two or more of these. Therefore, the term "parts" in the following description may be replaced with "component, piece," "member," "structure," "assembly," etc., or may be omitted. For example, the leg part 14 may be expressed as a leg part, leg member, leg structure, leg assembly, etc., or simply as a leg. Similarly, the arm part 15 may be expressed as an arm part, arm member, arm structure, arm assembly, etc., or simply as an arm. The same applies to the other parts.

[0016] (2. About the leg parts) 2 shows an exploded schematic diagram of a knee part 141, a thigh part 142, and a lower leg part 143, which are among the multiple parts that make up the leg part 14. The knee part 141 includes parts 141A to 141D. The thigh part 142 includes parts 142A to 142L. The lower leg part 143 includes parts 143A to 143H. For ease of understanding, the connections between these parts are shown with dashed lines in the drawing.

[0017] (2-1. Knee part configuration) The part 141A is a thigh holding part that can hold the thigh part 142. The part 141A extends into the thigh part 142 and supports the thigh part 142, and therefore may be referred to as a thigh supporting part, a thigh skeleton part, or the like.

[0018] The part 141B is a lower leg holding part that can hold the lower leg part 143. The part 141B extends into the lower leg part 143 and supports the lower leg part 143, and therefore may be referred to as a lower leg supporting part, a lower leg skeleton part, or the like.

[0019] Parts 141C and 141D are connected to each other to form a pair of clamping parts that rotatably clamp parts 141A and 141B. In this configuration, thigh part 142 rotates when part 141A rotates relative to parts 141C and 141D, and crus part 143 rotates when part 141B rotates. From this perspective, parts 141C and 141D may be referred to as knee main body parts or the like.

[0020] (2-2. Thigh part configuration) Part 142A is a thigh internal structure inner part that constitutes part of the inner side of the internal structure of thigh part 142. Part 142B is a thigh internal structure outer part that constitutes part of the outer side of the internal structure of thigh part 142. Parts 142A and 142B are connected to each other. As will be described in detail later, parts 142A and 142B are held so that they can rotate relative to parts 141C and 141D, and the range of motion (movable range) due to this rotation is limited by inserting part 141A through them.

[0021] Part 142C is a thigh exterior part that forms part of the exterior of thigh part 142, and can also be called a thigh inner exterior part that can be attached to part 142A. Part 142D is a thigh exterior part that forms another part of the exterior of thigh part 142, and can also be called a thigh outer exterior part that can be attached to part 142B. Parts 142C and 142D form a substantially continuous surface at the rear upper part of the thigh by being attached to parts 142A and 142B, respectively, and therefore can collectively be called thigh upper rear parts.

[0022] Part 142E is a thigh exterior part that forms another part of the exterior of thigh part 142, and can form a substantially continuous surface with parts 142C and 142D below them, so it can also be called a thigh rear lower part. As will be described in detail later, part 142E is rotatably sandwiched between parts 142C and 142D.

[0023] Part 142F is a thigh exterior part that forms another part of the exterior of thigh part 142, and can be attached to the upper outer walls of parts 142A and 142B from the front, so it can also be called a thigh front upper part. Part 142G is a thigh exterior part that forms another part of the exterior of thigh part 142, and can be attached to part 141A below part 142F from the front, so it can also be called a thigh front lower part. As will be described in detail later, parts 142F and 142G can form a substantially continuous surface.

[0024] Part 142H is a thigh exterior part that forms another part of the exterior of thigh part 142, and is configured to be able to be locked by parts 142C and 142D. Part 142H is located above parts 142C and 142D at the rear of doll body 1, and so can also be called a buttocks part.

[0025] Parts 142I to 142K form the hip joint structure of the doll body 1. Part 142I supports part 142B from above. Part 142J is connected to part 142I so that it can rotate left and right (or inward and outward). Part 142K is connected to part 142J so that it can rotate back and forth. Part 142K is also connected to waist 13 on the side opposite to part 142J. With this structure, leg parts 14 are held so that they can rotate back and forth and / or left and right relative to waist 13.

[0026] Part 142L is a thigh exterior part that forms another part of the exterior of thigh part 142, and is held rotatably from below relative to part 142J on the inside of the upper thigh. Details will be described later, but part 142L can also be said to be an upper inner thigh part located more inside than part 142A, and can also be said to be a sealing part that seals the internal structure so that it cannot be seen from the outside.

[0027] (2-3. Composition of lower leg parts) Part 143A is a lower leg exterior part that forms part of the exterior of lower leg part 143, and can also be called an inner upper part of the lower leg because it is attached to the inside of the upper part of part 141B. Part 143B is a lower leg exterior part that forms another part of the exterior of lower leg part 143, and can also be called an outer upper part of the lower leg because it is attached to the outside of the upper part of part 141B. Parts 143A and 143B are connected to each other, and form a substantially continuous surface at their rear parts, presenting a region equivalent to the calf.

[0028] Part 143C is a lower leg exterior part that forms another part of the exterior of lower leg part 143, and can also be called a lower leg part because it is engaged with and locked to the lower part of part 141B. Part 143D is connected to part 143C from below, and although its description is omitted here, it rotatably supports foot part 144 (see FIG. 1).

[0029] Part 143E is a lower leg exterior part that forms part of the exterior of lower leg part 143, and since it is attached to the upper front part of part 141B, it can also be called a lower leg upper front part.

[0030] Parts 143F to 143H are decorative parts attached to part 143E. Part 143F is attached to part 143E from the front. Part 143G is attached to part 143F from above so as to be rotatable. Part 143H is attached to the inner wall of part 143G.

[0031] Although the individual parts constituting the leg part 14 have been described individually here, some of these parts may be formed integrally. For example, two parts that are fixedly connected to each other and do not change their relative positions (parts 142B and 142I, parts 143G and 143H, etc.) may be formed integrally.

[0032] (3. Rotation of the leg parts) Fig. 3(A) shows a partial cross-sectional view in a side view of the leg part 14 in an extended state (a state in which the lower leg part 143 is in a forward position within its range of motion). Fig. 3(B) similarly shows a partial cross-sectional view of the leg part 14 in a partially rotated state (a state in which the knee part 141 and the lower leg part 143 are rotated backward relative to the thigh part 142). Fig. 3(C) similarly shows a partial cross-sectional view of the leg part 14 in a bent state (a state in which the lower leg part 143 is in a backward position within its range of motion).

[0033] For ease of understanding, in the drawing, the actual structure of the lower leg part 143 is shown, the outlines of parts 141C (or 141D) and 142 are shown by dashed lines, and the cross-sectional structures of parts 141A, 142E, and 142G are shown.

[0034] As shown in FIGS. 3A to 3C, part 141A includes first extension 141A1 and second extension 141A2 extending into thigh part 142. First extension 141A1 is provided so as to be engageable with part 142E, which is rotatably sandwiched between parts 142C and 142D. Second extension 141A2 is provided in front of first extension 141A1, and part 142G is attached to second extension 141A2. Part 141A is also provided with a substantially elliptical opening 142A3, through which the aforementioned parts 142A and 142B (see FIG. 2) are inserted and held. The portion connecting parts 142A and 142B and through which opening part 141A3 is inserted is indicated as part 91 in the figures.

[0035] With this configuration, the parts 142A and 142B are held so as to be rotatable relative to the parts 141C and 141D, and the range of motion due to the rotation is limited by inserting them through the opening 142A3. Therefore, the range of motion of the thigh part 142 relative to the knee part 141 is narrower than the range of motion of the lower leg part 143 relative to the knee part 141.

[0036] Now consider the case where the state of FIG. 3(A) is changed to the state of FIG. 3(B), i.e., the case where the thigh part 142 is rotated relative to the knee part 141 in a direction approaching the lower leg part 143. In this case, the first extension part 141A1 moves away from the inner wall of the part 142E serving as the thigh rear lower part. Therefore, the part 142E can be recessed relative to the outer shapes of the parts 142C and 142D serving as the thigh rear upper part. On the other hand, the part 142G serving as the thigh front lower part is attached to the second extension part 141A2. Therefore, in this case, the part 142G protrudes relative to the outer shape of the part 142F serving as the thigh front upper part.

[0037] 3(C), that is, when the lower leg part 143 is rotated to a position where the rear part of the lower leg part 143 comes into contact with part 142E, which serves as the thigh rear lower part. As described above, in the state of FIG. 3(B), part 142E is capable of being recessed relative to the outer shapes of parts 142C and 142D, which serve as the thigh rear upper parts. Therefore, when the rear part of the lower leg part 143 comes into contact with part 142E, part 142E is recessed due to the pressure caused by this contact.

[0038] Therefore, with this structure, the range of motion of the lower leg part 143 is increased, and it is possible to form a posture in which the lower leg part 143 and the thigh part 142 are closely attached (for example, a sporty posture such as a crouching pose).

[0039] Next, consider the case where the thigh part 142 is rotated relative to the knee part 141 from the state shown in FIG. 3(C) to the state shown in FIG. 3(A), i.e., where the thigh part 142 is rotated relative to the knee part 141 in a direction away from the lower leg part 143. In this case, the first extension part 141A1 contacts and presses against the inner wall of the part 142E serving as the thigh rear lower part. As a result, the part 142E is pushed outward, thereby forming a continuous surface with the parts 142C and 142D serving as the thigh rear upper part. Meanwhile, the part 142G serving as the thigh front lower part is attached to the second extension part 141A2. Therefore, in this case, the part 142G forms a continuous surface with the part 142F serving as the thigh front upper part.

[0040] Fig. 4(A) shows the state of the doll body 1 in a closed-leg posture with respect to the hip joint structure (parts 142I to 142K) and the surrounding area of ​​the thigh part 142. Fig. 4(B) shows the state of the doll body 1 in an open-leg posture with the thigh part 142 rotated in the direction of arrow A11 from the state of Fig. 4(A).

[0041] As described above, part 142L is rotatably held from below relative to part 142J on the inside of the upper thigh, and the internal structure is sealed inside part 142A so that it cannot be seen from the outside. Here, in the closed-leg posture (see FIG. 4(A)), most of part 142L is housed within parts 142C and 142F. On the other hand, in the open-leg posture (see FIG. 4(B)), part 142L rotates in the direction of arrow A12 and is partially exposed as its tip slides while engaging with part 142A (and 142C) (i.e., even in the open-leg posture, the tip of part 142L is located inside part 142A), and as a result, part 142L protrudes outward.

[0042] Generally, a gap may be formed between two parts that can rotate relative to each other to prevent interference between them, and the internal structure may be visible through the gap. According to the above-described configuration, part 142L seals the internal structure inside part 142A even in the spread-leg posture, making it impossible to see from the outside, which may be advantageous in improving the design of doll body 1.

[0043] (4. Summary of leg parts configuration) One of the body parts that make up the doll body 1 according to this embodiment is the leg part 14, which includes a knee part 141, a thigh part 142, and a lower leg part 143. The thigh part 142 is rotatable relative to the knee part 141, and in this embodiment includes upper thigh rear parts (parts 142C and 142D) and a lower thigh rear part (part 142E). The lower leg part 143 is rotatable relative to the knee part 141, and is attached to the knee part 141 so that the rear part of the lower leg part 143 can rotate to a position where it comes into contact with the lower thigh rear part (part 142E). In this embodiment, the range of motion of the thigh part 142 relative to the knee part 141 is narrower than the range of motion of the lower leg part 143 relative to the knee part 141.

[0044] Here, the thigh rear lower part (part 142E) is held so that the following is true: When the thigh part 142 is rotated relative to the knee part 141 in a direction that brings it closer to the crus part 143, the thigh rear lower part (part 142E) can be recessed into the thigh rear upper parts (parts 142C and 142D). When the thigh part 142 is rotated relative to the knee part 141 in a direction that moves it away from the crus part 143, the thigh rear lower part (part 142E) forms a continuous surface with the thigh rear upper parts (parts 142C and 142D).

[0045] In this embodiment, the knee part 141 includes a first extension part 141A1 that extends into the thigh part 142. When the thigh part 142 is rotated relative to the knee part 141 in a direction that brings it closer to the crus part 143, the first extension part 141A1 moves away from the inner wall of the thigh rear lower part (part 142E), which allows the thigh rear lower part (part 142E) to be recessed into the thigh rear upper parts (parts 142C and 142D). Furthermore, when the thigh part 142 is rotated relative to the knee part 141 in a direction away from the crus part 143, the first extension part 141A1 comes into contact with and presses against the inner wall of the thigh rear lower part (part 142E), causing the thigh rear lower part (part 142E) to form a continuous surface with the thigh rear upper parts (parts 142C and 142D). With this configuration, when the thigh part 142 is rotated, the above-mentioned aspect of the thigh rear lower part (part 142E) (i.e., the thigh rear lower part (part 142E) forms a recess in the thigh rear upper parts (parts 142C and 142D) and the formation of a continuous surface with the thigh rear upper parts (parts 142C and 142D)) can be appropriately realized.

[0046] According to this embodiment, the range of motion of the lower leg part 143 is increased, and it is possible to realize a doll body 1 that can assume a pose in which the lower leg part 143 and the thigh part 142 are closely attached (for example, a sporty pose such as a crouching pose). Therefore, this embodiment is advantageous in diversifying the poses that the doll body 1 can assume.

[0047] In this embodiment, the thigh part 142 further includes a thigh front upper part (part 142F) and a thigh front lower part (part 142G). The thigh front lower part (part 142G) is held so that the following is true: When the thigh part 142 is rotated relative to the knee part 141 in a direction that brings it closer to the lower leg part 143, the thigh front lower part (part 142G) protrudes relative to the thigh front upper part (part 142F). When the thigh part 142 is rotated relative to the knee part 141 in a direction that moves it away from the lower leg part 143, the thigh front lower part (part 142G) and the thigh front upper part (part 142F) form a continuous surface.

[0048] In this embodiment, the knee part 141 further includes a second extension 141A2 that extends into the thigh part 142. The thigh front lower part (part 142G) is held by this second extension 141A2. With this configuration, when the thigh part 142 is rotated, the aforementioned behavior of the thigh front lower part (part 142G) (i.e., the thigh front lower part (part 142G) protruding relative to the thigh front upper part (part 142F) and forming a continuous surface with the thigh front upper part (part 142F)) can be appropriately realized. As a result, it is possible to express the degree of thigh tension (a behavior similar to the muscle movement of a human body) when the lower leg part 143 and the thigh part 142 are brought close to each other, which can further contribute to the diversification of the poses that the doll body 1 can assume.

[0049] In this embodiment, the part 141A is provided with extending portions 141A1 and 141A2 separately, thereby preventing interference with other parts. In another embodiment, the extending portions 141A1 and 141A2 may be provided as a single extending portion.

[0050] (5. About the arm parts) 5 is an exploded schematic diagram showing elbow part 151, forearm part 153, and hand part 154, which are among the multiple parts that make up arm part 15. Elbow part 151 includes parts 151A to 151D. Forearm part 153 includes parts 153A to 153H. Hand part 154 includes parts 154A to 154C. For ease of understanding, the connections between these parts are shown with dashed lines in the drawing.

[0051] (5-1. Elbow part configuration) The part 151A is an upper arm holding part that can hold the upper arm part 152. The part 151A extends into the upper arm part 152 and supports the upper arm part 152, and therefore may be referred to as an upper arm supporting part, an upper arm skeletal part, or the like.

[0052] Part 151B is a forearm holding part capable of holding forearm part 153, and includes a shaft 151B1 for realizing this holding, as will be described in detail later. Part 151B extends into forearm part 153 to support forearm part 153, and therefore may be referred to as a forearm supporting part, a forearm skeletal part, or the like.

[0053] Parts 151C and 151D are connected to each other to form a pair of clamping parts that rotatably clamp parts 151A and 151B. In this configuration, the rotation of part 151A relative to parts 151C and 151D causes upper arm part 152 to rotate, and the rotation of part 151B causes forearm part 153 to rotate. From this perspective, parts 151C and 151D may be referred to as elbow main body parts or the like.

[0054] (5-2. Forearm Parts Configuration) Part 153A is a connecting part for connecting forearm part 153 to part 151B from below, and includes a ring part 153A1 and a holding part (or shaft part) 153A2 for making a part of forearm part 153 rotatable. As will be described in detail later, part 153A is rotatably held by inserting shaft part 151B1 of part 151B into ring part 153A1.

[0055] Part 153B is configured so that ring portion 153A1 of part 153A can fit into its inner wall, and is connected to part 153B from below (the connection is achieved by inserting shaft portion 151B1 through part 153B together with ring portion 153A1). Part 153C is a decorative part that can be attached to part 153B from the outside. Parts 153B and 153C form part of the exterior of forearm part 153 as forearm exterior parts, and because they are located on the torso 12 side (inside), they can also be called forearm interior parts.

[0056] Part 153D is a forearm exterior part that forms another part of the exterior of forearm part 153, and is connected to part 153B. As will be described in detail later, part 153D is provided with a notch 153D1 that allows part of forearm part 153 to be rotatable, and part 153A is held so that holding part 153A2 is inserted through notch 153D1.

[0057] Part 153E is held by holding part 153A2 on the opposite side of part 153D from part 153A. Part 153F is a decorative part that can be attached to part 153E from the outside. Parts 153E and 153F form another part of the exterior of forearm part 153 as forearm exterior parts, and because they are located on the opposite side (outside) from the torso part 12 side, they can also be called forearm outer part parts.

[0058] It can be said that the outer shape of the forearm itself is substantially formed by parts 153B to 153D, and parts 153E and 153F form accessory equipment. Therefore, part 153D can be expressed as a forearm outer part, and parts 153E and 153F can be expressed as equipment parts (for example, armor parts, shield parts, gauntlet parts, etc.) or decorative parts.

[0059] Parts 153G and 153H are decorative parts additionally provided on the rear of the forearm. Part 153G is sandwiched between parts 153B and 153D, and part 153H is attached to the tip of part 153G.

[0060] (5-3. Composition of hand parts) Part 154A is a hand body part. Part 154B is a decorative part that is attached to part 154A and decorates a part of the back of the hand.

[0061] Parts 154C and 154D form the wrist joint structure of the doll body 1. Part 154C connects to part 154A so that it can rotate in the wrist circumferential direction (direction d2, described below). Part 154D connects to part 154C so that it can rotate in the front-to-back direction, and is connected to part 153B from below so that it can rotate in the wrist circumferential direction. With this configuration, part 154A, which is a hand main body part, is held so that it can rotate in the wrist circumferential direction and / or the front-to-back direction. From this perspective, parts 154C and 154D can be collectively referred to as wrist parts.

[0062] Although the constituent parts of the arm part 15 have been described individually here, some of these parts may be integrally formed. For example, two parts that are fixedly connected to each other and do not change their relative positions (parts 153B and 153C, parts 154A and 154B, etc.) may be integrally formed.

[0063] (6. Rotation of arm parts) 6(A) and 6(B) are perspective views of the forearm part 153 and the hand part 154. Fig. 6(A) shows a state in which the palm-equivalent portion of part 154A, which is a hand main body part, faces inward (the same direction as parts 153B and 153C, which are forearm exterior parts). Fig. 6(B) shows a state in which part 154A is rotated in the wrist circumferential direction, so that the palm-equivalent portion faces backward.

[0064] For ease of understanding, in the drawing, the direction in which the forearm part 153 extends is shown as a first direction d1, and the circumferential direction (wrist circumferential direction) about the axis of the first direction d1 is shown as a second direction d2.

[0065] 5 together with FIGS. 6(A) and 6(B), in forearm part 153, shaft 151B1 of part 151B is inserted through ring 153A1 of part 153A. In other words, ring 153A1 is provided around shaft 151B1, which allows part 153A (and additionally holding part 153A2) to rotate in second direction d2.

[0066] Part 153D also has a notch 153D1 for inserting holding portion 153A2, which allows holding portion 153A2 to rotate in accordance with the rotation of part 153A. Parts 153E and 153F, which are forearm outer parts, are held at one end by part 154C and at the other end by holding portion 153A2.

[0067] 6(A) to the state of Fig. 6(B), that is, when parts 154C and 154D are used as wrist parts to rotate hand part 154 in the direction of arrow A21 relative to forearm part 153. In this case, part 154C rotates in the direction of arrow A21 together with hand part 154, causing parts 153E and 153F connected to part 154C to also rotate in the direction of arrow A21.

[0068] As described above, part 153D has notch 153D1 to allow rotation of holder 153A2 of part 153A. Therefore, as parts 153E and 153F rotate, holder 153A2 that holds them also rotates in the direction of arrow A21. That is, when hand part 154 is rotated in the direction of arrow A21 relative to forearm part 153 by parts 154C and 154D that realize the wrist joint structure, parts 153E and 153F as outer forearm parts also rotate in the direction of arrow A22. In other words, parts 153E and 153F act as rotating parts of forearm part 153 that rotate together with the rotation of hand part 154.

[0069] Generally, when a human rotates their wrist, the forearm can also rotate partially, and with the above-described configuration, such behavior can also be expressed with the doll body 1. Therefore, this embodiment is advantageous in diversifying the poses that the doll body 1 can assume.

[0070] (7. Summary of arm parts configuration) Another of the body parts that make up the doll body 1 according to this embodiment is the arm part 15, which includes an upper arm part 152, a forearm part 153, and a hand part 154. The forearm part 153 is rotatable relative to the upper arm part 152. The hand part 154 is rotatable relative to the forearm part 153. Here, the forearm part 153 includes a rotating part that rotates together with the rotation of the hand part 154 relative to the forearm part 153. In this embodiment, the forearm part 153 includes inner forearm parts (parts 153B and 153C) and outer forearm parts (parts 153E and 153F), and the outer forearm parts (parts 153E and 153F) act as the rotating part.

[0071] In this embodiment, the arm part 15 further includes an elbow part 151 that rotatably connects the upper arm part 152 and the forearm part 153. The hand part 154 includes a hand main body part (part 154A) and wrist parts (parts 154C and 154D) located on the forearm part 153 side, and is configured such that the hand main body part (part 154A) and the wrist parts (parts 154C and 154D) are rotatably connected to each other.

[0072] Here, the direction in which the forearm part 153 extends is defined as a first direction d1, and the circumferential direction (circumferential direction of the wrist) about the first direction d1 is defined as a second direction d2. The hand main body part (part 154A) is connected to the forearm part 153 so as to be rotatable at least in the second direction d2. The outer forearm parts (parts 153E and 153F) are held at one end by the wrist parts (parts 154C and 154D), and are held at the other end by the elbow part 151 so as to be rotatable in the second direction d2.

[0073] In this embodiment, elbow part 151 includes a first part (part 151A) that supports upper arm part 152 and a second part (part 151B) that supports forearm part 153 and is rotatable relative to the first part (part 151A). The second part (part 151B) includes a shaft 151B1 that extends in first direction d1, and forearm outer parts (parts 153E and 153F) are held rotatably relative to shaft 151B1. Forearm part 153 also includes a connecting part (part 153A) that connects shaft 151B1 and forearm outer parts (parts 153E and 153F). The connecting part (part 153A) includes a ring portion 153A1 that is attached to the shaft portion 151B1 so as to be rotatable in the second direction d2, and a holding portion 153A2 that extends from the ring portion 153A1 and holds the outer forearm part (parts 153E and 153F).

[0074] Generally, when a human rotates their wrist, the forearm can also rotate partially. According to this embodiment, such behavior can be expressed with the doll body 1, which is advantageous in diversifying the poses that the doll body 1 can assume.

[0075] (8. Summary) According to the above embodiment, the doll body 1 is configured by directly or indirectly connecting individual body parts to one another, and at least two of the multiple body parts are connected to one another so that they can rotate relative to one another. In this configuration, one body part is configured to partially rotate, swing, or deform when the other body part is rotated. With this structure, as can be seen from the leg parts 14 and arm parts 15 exemplified in this specification, for example, it is possible for the doll body 1 to assume more human-like poses or change its pose, which is advantageous for diversifying the poses that the doll body 1 can assume.

[0076] The invention is not limited to the above-described embodiment, and various modifications and variations are possible within the scope of the gist of the invention. [Explanation of symbols]
