In the present embodiment, the rotating mannequin, the housing 600, the drive device, such as a motor and gears, and a revolving shaft 500 extending to the upper portion of the housing 600, the outer side from the revolving shaft 500 Body supports 410 and 420 extending to the body portion 300 is coupled to the body support (410, 420).

Here, the body 300 is composed of the upper body 310 and the lower body 320 is displayed by the top is coated and displayed, the body support (410, 420) is the idle shaft 500 and It consists of an upper support 410 for connecting the upper body 310, and a lower support 420 for connecting the idle shaft 500 and the lower body 320.

First, the durable structure of the housing 600 is shown in FIG. The housing 600 includes a lower portion of the idle shaft 500 and an idle motor 610 for rotating the idle shaft 500.

The idle shaft 500 is located on the outer side of the upper body idle shaft 510 of the hollow upper body shaft 510, and extends longer than the upper end of the upper body idle shaft 510 and the And a lower revolving shaft 520 extending longer than the lower end of the upper revolving shaft 510, and between the upper revolving shaft 510 and the lower revolving shaft 520 for a smooth relative rotation. (Not shown) may be installed.

Meanwhile, a first bevel gear 621 is coupled to the rotation shaft of the idle motor 610, and the first bevel gear 621 is vertically connected to the second bevel gear 622 and the third bevel gear 623. do.

The lower revolving axis input gear 624 is positioned on the upper portion of the second bevel gear 622 to rotate integrally on the coaxial. On the other hand, the outer circumferential surface of the lower idle revolution shaft 520 is provided with a lower idle revolution shaft drive gear 625 to be engaged with the lower idle revolution shaft input gear 624.

On the other hand, the upper bevel gear input gear 626 is positioned below the third bevel gear 623 to rotate integrally on the coaxial. In addition, the outer circumferential surface of the upper idle revolution shaft 510 is provided with an upper idle revolution drive gear 627 to be engaged with the upper idle revolution shaft input gear 626.

Accordingly, the lower idle shaft input gear 624, the second bevel gear 622, the third bevel gear 623, and the upper idle shaft input gear 626 are all coaxial, but the lower idle shaft input gear ( The rotation direction of the 624 and the second bevel gear 622 and the rotation direction of the third bevel gear 623 and the upper idle revolution input gear 627 are opposite to each other.

Rotation of the idle motor 610 is controlled by a controller.

In the upper portion of the housing 600, as shown in Figure 2, the upper body support portion 410 is extended to the outside of the upper revolution axis 510.

The upper support 410 is a horizontal portion (411, 412) extending to the outside of the upper idle revolution shaft 510, and vertically bent upwards extending approximately at the letter A from the outer end of the horizontal portion (411, 412) An upper body rotating motor 414 (see FIG. 4A) is built in the vicinity of an end portion of the vertical portion 413, and a coupling protrusion 415 is provided at an upper end portion of the upper body rotating motor 414. It is provided.

1 and 4A, the upper body support part 410 is coupled to the upper body part 310. The upper body part 310 is a part of the upper body part that is to be displayed. The upper body has a shape, the center is provided with a vertical vertical axis 311 extending up and down, and the coupling groove 312 corresponding to the shape of the coupling protrusion 415 at the lower end of the upper vertical axis 311 Is formed.

Accordingly, when the upper body rotating motor 414 rotates, the upper body 310 rotates by coupling coupling of the upper coupling protrusion 415 and the upper coupling groove 312.

That is, the upper body vertical axis 311 and the vertical portion 413 forms a rotation axis of the upper body portion 310.

In this case, the horizontal parts 411 and 412 should be positioned below the lower end of the upper body part 310 so that the rotation of the upper body part 310 is not disturbed by the horizontal parts 411 and 412.

On the other hand, the lower body support 420 is extended to the outside of the lower body revolution shaft 520. The lower support 420 is a horizontal portion (421, 422) extending to the outside of the lower idle revolution shaft 520, and vertically bent downwardly extending in the bottom of the horizontal portion (421, 422) in an approximately "A" shape And a lower portion rotating motor 424 as shown in FIG. 4B, and a coupling protrusion 425 at a lower end portion of the lower portion rotating motor 424.
