[0120] The audio output module 1500 can provide any form of audio output to a user. For example, the audio output module 1500 can provide brain stimulation to a user by outputting an optimal sound source and / or binaural beat for a massage mode provided by the massage device 100. The audio output module 1500 can output a sound signal received through a network (not shown) or stored in an internal / external storage medium (not shown).

[0121] For example, the audio output module 1500 can output a sound source based on a control of a user terminal through a network connection (e.g., a Bluetooth connection, etc.) with the user terminal. In addition, the audio output module 1500 can output any form of sound signal generated in association with an operation of the massage device 100.

[0122] The massage device 100 according to an embodiment of the present application can include a network connection part 1600. The network connection part 1600 can communicate with modules inside the massage device 100, external massage devices 100, and / or user terminals through any form of network.

[0123] The network connection part 1600 can include a wired / wireless connection module for connecting a network. As a wireless connection technology, for example, a wireless LAN (WLAN) (Wi-Fi), a wireless broadband (Wibro), a world interoperability for microwave access (Wimax), a high speed downlink packet access (HSDPA), etc. can be employed.

[0124] As a wired connection technology, for example, a digital subscriber line (XDSL), fibers to the home (FTTH), power line communication (PLC), etc. can be utilized. In addition, the network connection part 1600 can include a short distance communication module capable of transmitting and receiving data with some devices or terminals in a short distance. For example, as a short range communication technology, Bluetooth, a radio frequency identification technology (RFID), infrared data association (IrDA), ultra wideband (UWB), ZigBee, etc. can be utilized, but are not limited thereto.

[0125] As described above, the massage device 100 according to an embodiment of the present application can include a massage module 1700. That is, the massage module 1700 is a structure to provide a user with a mechanical stimulus, and the massage module 1700 can be moved along the frame part 1100.

[0126] The massage device 100 according to an embodiment of the present application can include a main frame 1100. As described above, Figures 1 to 3 the main frame 1100 can provide a path in which the massage module 1700 can be moved.

[0127] The control part 1200 can provide a massage by controlling an operation of the massage module 1700 to apply a mechanical stimulus to a user.

[0128] The control part 1200 can move the massage module 1700 in a direction of an X axis, a Y axis, and a Z axis, etc. The control part 1200 can make the massage ball advance forward or retreat backward on the X axis, the Y axis, and the Z axis. Alternatively, the control part 1200 can rotate the massage ball around the X axis, the Y axis, and the Z axis as a center.

[0129] The massage device 100 according to an embodiment of the present application can include a sensor portion 1800. At this time, the sensor portion 1800 can include at least one sensor. For example, the sensor portion 1800 can include a touch sensor, a pressure sensor, an infrared sensor, an LED sensor, a light sensor, a Hall sensor, an electrostatic sensor, etc., but is not limited thereto.

[0130] The sensor portion 1800 can be used to acquire various information. For example, the sensor portion 1800 can be used to identify a user. That is, information about whether the user is seated, the user's body type, whether the user's body has an abnormality, etc. can be acquired. As another example, the sensor portion 1800 can be used to acquire biometric information. That is, fingerprint information, face information, voice information, iris information, weight information, electrocardiogram information, body composition information, etc. can be acquired, but is not limited thereto, and can include various biometric information.

[0131] As an optional embodiment, the massage device 100 can detect a contact area and / or a contact position with the user through the sensor portion 1800.

[0132] In addition, the massage device 100 can acquire shoulder position information of the user through the sensor portion 1800.

[0133] In addition, the massage device 100 can provide individualized massage according to information acquired through the sensor portion.

[0134] The leg massage portion 2000 can be a structure for massaging the user's legs. A leg accommodation space for accommodating the user's legs can be formed in the leg massage portion 2000. Referring to Figure 1 A plurality of leg massage portions 2000 can be provided, and the user's right foot and left foot can be accommodated in the plurality of leg massage portions 2000A, 2000B, respectively.

[0135] Specifically, each of the plurality of leg massage portions 2000A, 2000B can include a foot massage portion 2200 and a calf massage portion 2100, and can accommodate the user's right foot and left foot, respectively.

[0136] Figure 4 FIG. 2 is a view illustrating a leg massage portion of a massage device according to an embodiment of the present application, Figure 5 FIG. 3 is a view illustrating a lower area of a foot massage portion of a massage device according to an embodiment of the present application, Figure 6 FIG. 4 is a view illustrating each structure of a lower area of a foot massage portion formed in Figure 5 FIG. 5 is a view illustrating each structure of a lower area of a foot massage portion formed in

[0137] Referring to Figures 4 to 6 , the leg massage part 2000 according to the present application can include a lower leg massage part 2100 and a foot massage part 2200, and the foot massage part 2200 includes a foot case 2201 in which a user's foot can be inserted. A structure for driving the foot case 2201 to support the user's ankle movement is provided on the lower side of the foot case 2201. Hereinafter, this will be described in detail.

[0138] The foot massage part 2200 is composed of several main constituent elements to provide various rotation and stretching movements to the ankle. The foot massage part 2200 includes a first rotation shaft 2211 and a second rotation shaft 2212 responsible for rotation, and is equipped with a rotation plate 2220 and a driving transmission part 2240 for effectively transmitting the actions of these rotation shafts.

[0139] It also includes a support plate 2230 that fixes the foot and imparts movement stability, and a ball joint 2250 that allows the foot to move freely. Such constituent elements are stably supported by a bottom plate 2261 located at the lower part of the foot massage part 2200 and a fixing shaft 2262 fixed thereto, and each component is organically combined to enable smooth execution of the foot massage action.

[0140] The first rotation shaft 2211 is a constituent element of the foot massage part 2200 of the present application that effectively implements rotation and stretching movements of the ankle. The first rotation shaft 2211 is engaged with a power gear 2202 driven by a motor, and rotates in a clockwise or counterclockwise direction directly receiving rotational force from the motor. This rotational force is transmitted to the support plate 2230 and the foot case 2201 through the driving transmission part 2240, so that the foot case can move flexibly according to the ankle.

[0141] The first rotation shaft 2211 is designed in a hollow structure, and the second rotation shaft 2212 can be inserted into the inside thereof, so that a composite rotation and stretching movement can be performed, thus supporting various movements of the ankle. The first rotation shaft 2211 and the second rotation shaft 2212 are connected by a second clutch bearing 2272 at the upper part of the first rotation shaft 2211, and have a structure in which two shafts can be operated independently or in linkage.

[0142] The first rotation shaft 2211 is also supported by the fixing shaft 2262 fixed to the bottom plate 2261, which constitutes a lower support part. The first rotation shaft 2211 is connected to the fixing shaft 2262 through a bearing 2263, so that the first rotation shaft 2211 rotates smoothly.

[0143] The first rotating shaft 2211 and the rotating plate 2220 are connected by a first clutch bearing 2271. When rotating in a specific direction (e.g., when rotating counterclockwise), the rotating plate rotates together and transmits rotational force to the support plate 2230 and the foot housing 2201. When rotating in the opposite direction (e.g., when rotating clockwise), other movements can be achieved by fixing the rotating plate 2220. The socket 2252 of the ball joint 2250 is rotatably connected to the upper part of the first rotating shaft 2211, thereby supporting the free movement of the foot housing 2201.

[0144] Figure 7 Figures (a) to (c) are diagrams illustrating the drive of the clutch bearing in an embodiment of the present invention. (Refer to...) Figure 7 The structure of the clutch bearing applicable to this utility model is described in (a) to (c) below.

[0145] According to an embodiment of the present invention, the clutch bearing 2270 includes a first to a third clutch bearing 2271 to 2273. The first clutch bearing 2271 and the third clutch bearing 2273 can transmit rotational force when rotating counterclockwise, while the second clutch bearing 2272 can transmit rotational force when rotating clockwise.

[0146] like Figure 7 The clutch bearing 2270 shown in (a) may include an inner ring 2270a, an outer ring 2270b, a roller 2270c disposed between the inner ring 2270a and the outer ring 2270b, and a spring 2270d connecting the inner ring 2270a and the roller 2270c.

[0147] The second clutch bearing 2272 will be used as an example for explanation. The second clutch bearing 2272 is as follows... Figure 7 As shown in (b), when the inner ring 2270a rotates counterclockwise, the space between the outer ring 2270b and the inner ring 2270a decreases. In this case, since the space cannot be less than the outer diameter of the roller 2270c, the outer ring 2270b cannot rotate. Conversely, as... Figure 7 As shown in (c), when the inner ring 2270a rotates clockwise, the space between the outer ring 2270b and the inner ring 2270a is kept constant by the spring 2270d. In this case, the outer ring 2270b can rotate.

[0148] That is, according to the embodiments of the present invention, the second clutch bearing 2272 can be designed to transmit only clockwise rotation and not counterclockwise rotation.

[0149] On the other hand, unlike the second clutch bearing 2272, the first and third clutch bearings 2271 and 2273 can be designed to transmit only counterclockwise rotation and not clockwise rotation.

[0150] Detailed descriptions of the first to third clutch bearings 2271-2273 will be described later together with the related structural descriptions.

[0151] Referring again to Figure 5 , the second rotating shaft 2212 is inserted into the hollow structure of the first rotating shaft 2211, so that the two rotating shafts can be linked or independently rotated. The second rotating shaft 2212 is connected to the first rotating shaft 2211 by the second clutch bearing 2272, which transmits rotational force only when the second rotating shaft 2212 rotates in the clockwise direction. Conversely, the first clutch bearing 2271 located between the first rotating shaft 2211 and the rotating plate 2220 transmits rotational force only when it rotates in the counterclockwise direction.

[0152] That is, the first clutch bearing 2271 transmits rotational force to the rotating plate 2220 only when it rotates in the counterclockwise direction, and the rotating plate 2220 is fixed when it rotates in the clockwise direction. Conversely, the second clutch bearing 2272 transmits rotational force of the first rotating shaft 2211 to the second rotating shaft 2212 only when it rotates in the clockwise direction.

[0153] As described above, by setting the rotational permission directions of the first clutch bearing 2271 and the second clutch bearing 2272 to be different, the second rotating shaft 2212 can operate together with the first rotating shaft 2211 or independently perform a rotational motion with respect to the first rotating shaft 2211.

[0154] The rotating plate 2220 is an element for realizing rotation and stretching of the ankle in the leg massage part 2200 of the present application, and is designed to receive rotational force in only a specific direction in a state in which the first rotating shaft 2211 is combined to the hollow of the rotating plate 2220.

[0155] The rotating plate 2220 is a constituent element for realizing rotation and stretching motion of the ankle in the leg massage part 2200, and receives driving force through the first rotating shaft 2211. The first clutch bearing 2271 is combined between the first rotating shaft 2211 and the rotating plate 2220, so that rotational force is transmitted to the rotating plate 2220 only when the first rotating shaft 2211 rotates in the counterclockwise direction. Through this structure, the rotating plate 2220 is selectively rotated according to the rotational direction of the first rotating shaft 2211.

[0156] A support plate 2230 is provided on the upper side of the rotating plate 2220 to support the foot housing 2201. A drive transmission unit 2240 is located between the rotating plate 2220 and the support plate 2230, and is designed to transmit the rotational motion of the rotating plate 2220 to the support plate 2230 and then to the foot housing 2201. When the rotating plate 2220 rotates, the drive transmission unit 2240 can transfer its motion to the support plate 2230 to help the foot housing 2201 perform stretching and rotational movements.

[0157] The support plate 2230 is disposed on the upper side of the rotating plate 2220, stably supporting the foot housing 2201 while performing rotational and swinging movements according to the rotation direction of the first rotating shaft 2211.

[0158] When the first rotating shaft 2211 rotates counterclockwise, the support plate 2230 rotates by receiving power from the rotating plate 2220. When the first rotating shaft 2211 rotates clockwise, since the rotating plate 2220 is fixed, only a swinging motion is performed. At this time, the swinging motion allows the ankle to move smoothly through the meshing between the rack 2243 and the semi-circular gear 2244.

[0159] Multiple ball bearings 2203 mounted on the foot housing 2201 abut against the upper surface of the support plate 2230 to support the foot housing 2201. A semi-circular gear 2244 is mounted on the lower surface of the support plate 2230. The semi-circular gear 2244 is designed to mesh with a rack 2243 connected to a sliding block 2242, allowing the support plate 2230 to swing. This allows adjustment of the ankle angle and enhances the massage effect through the swinging motion.

[0160] Figure 8 This is a diagram illustrating each structure of the drive transmission unit disposed between the rotating plate and the support plate in the foot massage part of this utility model.

[0161] Reference Figure 8 The drive transmission unit 2240 is disposed between the rotating plate 2220 and the support plate 2230, and performs the function of transmitting rotational or oscillating motion to the support plate 2230 according to the rotation direction of the first rotating shaft 2211. The drive transmission unit 2240 includes a guide 2241, a sliding block 2242, a rack 2243, and a semi-circular gear 2244. Each component realizes various movements of the support plate 2230 according to the rotation direction of the first rotating shaft 2211.

[0162] In detail, the guide portion 2241 is fixed to the rotation plate 2220, and the guide sliding block 2242 can move left and right according to the guide of the guide portion 2241. The guide portion 2241 can be formed to extend along the length direction of the rotation plate 2220 at both sides of the rotation plate 2220, thereby providing a path through which the sliding block 2242 can stably move. Thus, the sliding block 2242 can linearly move on the rotation plate 2220.

[0163] The rack 2243 is combined to the sliding block 2242, and the rack 2243 is engaged with the semicircular gear 2244 installed at the lower portion of the support plate 2230. Through the engagement of the rack 2243 and the semicircular gear 2244, the linear movement of the sliding block 2242 is transmitted to the semicircular gear 2244, which helps the angle adjustment of the support plate 2230, thereby guiding the oscillating movement of the support plate 2230.

[0164] When the first rotation shaft 2211 rotates in the clockwise direction, the rack 2243 and the semicircular gear 2244 are engaged, and the oscillating movement is performed by adjusting the angle of the support plate 2230, and conversely, when the first rotation shaft 2211 rotates in the counterclockwise direction, the rotation plate 2220 and the support plate 2230 rotate together, and thus the support plate 2230 performs the rotational movement.

[0165] A detailed driving of the support plate 2230 according to the rotation direction of the first rotation shaft 2211 will be described later.

[0166] Referring again to Figure 6 The ball joint 2250 is described as follows.

[0167] The ball joint 2250 of the present utility model performs an action of allowing the foot portion housing 2201 to move with respect to the support plate 2230 between the foot portion housing 2201 and the support plate 2230, and is composed of a ball head 2251 and a socket 2252.

[0168] The ball head 2251 is composed of a shaft 2251a and a ball 2251b portion combined at the lower end of the shaft 2251a. The shaft 2251a forms a shaft of the foot portion housing 2201 and plays a role of supporting the movement of the foot portion housing 2201, and through this combination, the movement of the foot portion housing 2201 is transmitted through the ball joint 2250.

[0169] The ball 2251b at the lower end is located at the lower portion of the ball head 2251 and is combined with the socket 2252. The ball 2251b portion is designed to be inserted into the upper portion of the socket 2252 and can be rotated at various angles in the socket 2252, thereby smoothly supporting the movement of the foot portion housing 2201 to be inclined or rotated. The socket 2252 is a shape surrounding the ball 2251b, and the inner space is formed to match the shape of the ball 2251b, thereby being freely rotatable.

[0170] The socket 2252 is a constituent element of the ball joint 2250 designed to accommodate the ball 2251b as a lower end portion of the ball head 2251 and rotatably support. The socket 2252, in combination with the support plate 2230, can rotate the ball head 2251 and move at various angles, and make the rotation and angle adjustment of the foot case 2201 smooth.

[0171] In addition, the socket 2252 is inserted into the hollow of the second rotation shaft 2212, and such a combination is achieved by a third clutch bearing 2273. The third clutch bearing 2273 is installed between the socket 2252 and the second rotation shaft 2212, and transmits rotational force only when rotating in a specific direction, and, like the first clutch bearing 2271, transmits only counterclockwise rotation. This is contrary to the function of the second clutch bearing 2272, which allows rotation in only the desired direction within the system.

[0172] The lower portion of the socket 2252 is also rotatably combined with the fixed shaft 2262, so that the entire ball joint 2250 can perform further rotation with the fixed shaft 2262 as the center. Through this structure, various movements of the foot case 2201 are smoothly performed, and the rotation and angle adjustment functions of the ankle are more effectively supported through the combination with the support plate 2230.

[0173] Figure 9 (a) and (b) of FIG. 1 are diagrams illustrating a motion conversion part of the present application that converts the rotational force of the first rotation shaft into linear motion of the sliding block. Figure 9 Each step of (a) of FIG. 1 corresponds to Figure 9 Each step of (b) of FIG. 1.

[0174] Referring to Figure 9 (a) and (b) of FIG. 1, the drive transmission part 2240 according to the present application can include a motion conversion part 2245. The motion conversion part 2245 includes a plurality of gears 2245a for converting the rotational force of the first rotation shaft 2211 into linear motion of the sliding block 2242. The plurality of gears can include a driving gear 2245a-1 and first and second driven gears 2245a-2, 2245a-3 engaged with both sides of the driving gear 2245a-1.

[0175] The driving gear 2245a-1, in a state of being combined with the first rotation shaft 2211 in the motion conversion part 2245, performs the role of transmitting the rotational force of the first rotation shaft 2211 to the first and second driven gears 2245a-2, 2245a-3. The central shaft s1 of the driving gear 2245a-1 is designed in an eccentric structure so that power is transmitted along an eccentric trajectory when rotating. Such an eccentric central shaft s1 is engaged with the driven gears 2245a-2, 2245a-3 and guides linear motion of the sliding block 2242.

[0176] The first driven gear 2245a-2 and the second driven gear 2245a-3 also have eccentric center shafts s2, s3, and each of the center shafts s2, s3 is fixed to the slider 2242. With this eccentric design, when the driving gear 2245a-1 rotates, the driven gears move together and linear motion in the left-right direction is formed on the slider 2242.

[0177] In particular, the center shaft s1 of the driving gear 2245a-1 is formed in a through portion 2242a located at the center of the slider 2242, which is designed to freely move the slider 2242 in the left-right direction.

[0178] In order for the left-right movement of the slider 2242 to proceed smoothly, the relationship between the driving gear center s1 and each of the driven gear centers s2, s3 is important. In particular, the sum of the distance from the driving gear center s1 to the first driven gear center s2 and the distance from the driving gear center s1 to the second driven gear center s3 is always the same as the distance between the first driven gear center s2 and the second driven gear center s3.

[0179] In addition, in order to smoothly maintain the engagement of the gears, even during the gear driving process, the driving gear center s1 and each of the driven gear centers s2, s3 should maintain the same height. This makes the engagement between the center shafts of each gear consistent when the slider 2242 moves horizontally, so that the slider 2242 can be accurately moved without shaking. When both conditions, i.e., the height consistency and the distance relationship, are satisfied, the slider 2242 performs accurate and smooth left-right movement, thereby ensuring stable operation of the entire mechanism.

[0180] Figure 10 is a diagram showing the process of linear motion of the slider Figure 9 transferred to the swinging motion of the support plate.

[0181] Referring to Figure 10 The rack 2243 combined with the slider 2242 moves left and right according to the linear motion of the slider 2242, and the rack 2243 engages and drives the semicircular gear 2244 attached to the support plate 2230.

[0182] The rack 2243 serves as a medium that transmits the linear motion of the slider 2242 to the semicircular gear 2244, and the semicircular gear 2244 rotates as the slider 2242 moves left and right. Since the semicircular gear 2244 is fixed to the lower surface of the support plate 2230, the linear motion of the rack 2243 is converted into rotational motion of the semicircular gear 2244, and in this process, the support plate 2230 performs a swinging motion centered on the first and second rotation axes 2211, 2212.

[0183] The gear combination as described above can accurately control the movement of the support plate according to the gear ratio of the rack 2243 and the half-circular gear 2244 and the combined angle. Therefore, the linear movement of the sliding block 2242 is converted into the swing movement of the support plate 2230 through the rack 2243 and the half-circular gear 2244, so that the stretching movement of the ankle can be achieved.

[0184] Referring again to Figure 5 , the operation of the first to third clutch bearings 2271, 2272, 2273 for performing the swing movement of the support plate 2230 will be described. This is a core element that can make the support plate 2230 perform only the swing movement without rotation.

[0185] First, the first rotating shaft 2211 rotates in the clockwise direction, and thus the first clutch bearing 2271 functions as a structure that transmits only counterclockwise rotation. Since the first clutch bearing 2271 allows only counterclockwise rotation, when the first rotating shaft 2211 rotates in the clockwise direction, the rotating plate maintains a fixed state. In this fixed state, the sliding block 2242 moves left and right by the rotational force of the first rotating shaft 2211, and the swing movement of the support plate 2230 is guided by the half-circular gear 2244 engaged with the rack 2243.

[0186] The first rotating shaft 2211 is connected to the second rotating shaft 2212 through the second clutch bearing 2272. In contrast to the first clutch bearing 2271, the second clutch bearing 2272 has a characteristic of allowing only clockwise rotation. Therefore, when the first rotating shaft 2211 rotates in the clockwise direction, the second rotating shaft 2212 also rotates in the clockwise direction through the second clutch bearing 2272.

[0187] The second rotating shaft 2212 is connected to the socket 2252 of the ball joint 2250 through the third clutch bearing 2273. Like the first clutch bearing 2271, the third clutch bearing 2273 transmits only counterclockwise rotation. Therefore, even if the second rotating shaft 2212 rotates in the clockwise direction, the third clutch bearing 2273 does not transmit the clockwise rotation to the socket 2252. As a result, the socket 2252 of the ball joint 2250 maintains a fixed state and does not rotate. Through the ball 2251b moving with respect to this fixed socket 2252, the support plate 2230 can perform only the swing movement without rotation.

[0188] Figure 11 is a diagram showing a process in which the counterclockwise rotation of the first rotating shaft of the present utility model is transmitted to the rotating movement of the support plate.

[0189] Referring again to Figure 11When the first rotating shaft 2211 rotates in the counterclockwise direction, this rotational motion is transmitted to the rotating plate 2200 through the first clutch bearing 2271. The first clutch bearing 2271 is provided to transmit only the counterclockwise direction rotation, and thus when the first rotating shaft 2211 rotates in the counterclockwise direction, the rotating plate 2200 also rotates in the counterclockwise direction.

[0190] The sliding block 2242 fixed to the rotating plate 2200 rotates in the same direction as the rotating plate 2200 without performing a separate left-right linear motion in the state of being integrated with the rotating plate 2200. Through this rotational motion, the rack 2243 attached to the sliding block 2242 rotates together with the rotating plate 2200, and the rack 2243 is engaged with the semicircular gear 2244, and thus the rotational motion is transmitted to the semicircular gear.

[0191] The semicircular gear 2244 fixed to the lower surface of the support plate 2230 performs a corresponding rotational motion as the rack 2243 rotates. This rotational motion makes the semicircular gear 2244 itself rotate in the horizontal plane, and as a result, the rotational motion is transmitted to the support plate 2230. Here, the rotation of the semicircular gear 2244 refers to the rotational motion in the horizontal plane, not the circumferential direction rotation of the gear.

[0192] That is, the counterclockwise direction rotation of the first rotating shaft 2211 is converted into the rotational motion of the support plate 2230 through the rotating plate 2200, the sliding block 2242, the rack 2243, and the semicircular gear 2244. Thereby, the ankle rotational motion can be made.

[0193] Referring again to Figure 5 An operation of the first to third clutch bearings 2271, 2272, and 2273 for performing this rotational motion of the support plate 2230 will be described.

[0194] First, the counterclockwise direction rotation of the first rotating shaft 2211 is transmitted to the rotating plate 2200 through the first clutch bearing 2271. Since the first clutch bearing 2271 is provided to transmit only the counterclockwise direction rotation, when the first rotating shaft 2211 rotates in the counterclockwise direction, the rotating plate 2200 also rotates in the counterclockwise direction.

[0195] The rotating plate 2200 and the sliding block 2242 are integrated, and the sliding block 2242 rotates together with the rotating plate. In this state, the rack 2243 combined to the sliding block 2242 is engaged with the semicircular gear 2244, and thus the rotational motion is transmitted to the semicircular gear 2244. Since the semicircular gear 2244 is fixed to the support plate 2230, the rotational motion of the rack 2243 is converted into the rotational motion of the support plate 2230.

[0196] The socket 2252 is combined with the support plate 2230, and when the support plate 2230 rotates, the socket 2252 also rotates together. The counterclockwise rotation of the socket 2252 is transmitted to the second rotating shaft 2212 through the third clutch bearing 2273. The third clutch bearing 2273 has a characteristic of transmitting only counterclockwise rotation, so that the rotational motion of the socket 2252 is transmitted only to the second rotating shaft 2212 and the rotation in other directions is blocked.

[0197] The second rotating shaft 2212 is connected with the first rotating shaft 2211 through the second clutch bearing 2272, which is provided to transmit only clockwise rotation. Therefore, even if the second rotating shaft 2212 rotates in the counterclockwise direction, power is not transmitted to the first rotating shaft 2211, and the second rotating shaft 2212 rotates alone. Therefore, the first rotating shaft 2211 and the second rotating shaft 2212 can independently rotate at different speeds from each other.

[0198] The advantage of this structure is that it can stably operate even if the rotation speeds of the support plate 2230 and the rotating plate 2200 are different from each other. Since the support plate 2230 adjusts the rotation speed by the frictional force with the ball 2203 installed in the foot housing 2201, the difference in the rotation speed is allowed.

[0199] Figure 12 is a view showing that the rotation and the swing motion of the support plate of the present utility model are sequentially performed.

[0200] Referring to Figure 12 , the support plate 2230 alternately performs the rotation motion and the swing motion according to the rotation direction of the first rotating shaft 2211.

[0201] First, when the first rotating shaft 2211 rotates in the counterclockwise direction, the rotational force is transmitted to the rotating plate 2200 through the first clutch bearing 2271. Since the rotating plate and the sliding block 2242 are formed in one body, the rack 2243 fastened to the sliding block transmits the rotational motion to the support plate by driving the half circular gear 2244. The half circular gear 2244 fixed to the support plate 2230 rotates together with the support plate, and performs the ankle motion that smoothly rotates the foot housing 2250.

[0202] After that, when the first rotating shaft rotates in the clockwise direction, the first clutch bearing 2271 does not transmit the rotational force to the rotating plate, and the sliding block 2242 does not move and is positioned at the position fixed to the rotating plate 2200. In this state, the rack 2243 connected to the sliding block 2242 is engaged with the half circular gear 2244, so that the support plate 2230 performs the swing motion instead of the rotation. The swing motion makes the support plate sway back and forth, thereby providing the effect of helping the stretching of the ankle through the foot housing 2201.

[0203] Therefore, as Figure 12 indicated, the support plate 2230 can sequentially perform the rotation movement and the swing movement according to the rotation direction of the first rotation shaft 2211, thereby the ankle rotation and stretching effects can be provided.
