Description of the invention: [Technical field to which the invention belongs] The present invention relates to a massager for massaging a user's knee area. [Prior Art] Conventionally, there has been proposed a massage chair having a massage function for massaging a user's knee area while the user is sitting (for example, Patent Document 1). FIG. 5 shows an external view of a conventional massage chair of the first type. As shown in Figs. 5 (a) and-5 (b), a pivot 16 provided at the front end of the seat portion 12 is used as a rotation axis to rotatably mount an uneven knee support portion 14 having a massage function. When the user receives a massage, as shown in FIG. 5 (a), the knee support portion 14 is turned forward (horizontal direction), and the user's knee is placed in the recess of the knee support portion 14. On the other hand, when the user does not receive the massage, as shown in Fig. 5 (b), the lower knee support portion 14 turns downward. However, in order to allow the user to sit comfortably without receiving a massage, there are cases where some support is needed under the knee. In this case, although no massage is performed, as shown in FIG. 5 (a), the knee support portion 14 ^ is in a state in front of the steering seat portion 12. Therefore, the user's own knee is placed in the recess of the lower knee support portion 14, but it is difficult to move freely under the knee, so there is a problem of strong restraint. For this reason, a massage chair is also proposed (for example, Patent Document 2) to relieve the restraint of the user. FIG. 6 shows an external view of a conventional massage chair of the second type. As shown in Figs. 6 (a) and 6 (b), a support arm 31 is rotatably attached with a pivot shaft 34 provided at the front end of the seat portion 22 as a rotation shaft. Furthermore, the leg portion 25 is rotatably attached to a pivot shaft 26 provided in the center of the arm extending from the rear 200524573, * side forward in the support arm 31 as a rotation shaft. The external view of the footrest of the conventional 2nd massage chair shown in FIG. As shown in FIG. 7 (a), one surface of the foot placing portion 25 is formed with a concave-convex shape, and the massage surface 24 is formed on the other surface of the foot placing portion 25 as shown in FIG. 7 (b). Foot surface 35. When the user receives the massage, the foot setting portion 25 is rotated with the massage surface 24 as the upper surface, and when the user is not receiving the massage, the foot setting portion 25 is rotated with the foot surface 35 as the upper surface. With this, when the user has not received the # massage, the foot support surface 35 supports the lower knee. [Patent Document 1] Japanese Patent Laid-Open No. 8-257084 [Patent Document 2] Japanese Patent Laid-Open No. 2003-62024 [Summary of Invention] (Problems to be Solved by the Invention) However, the conventional massage shown in FIG. 6 In order to prevent the chair from interfering with the floor when the legrest 25 is rotated, the length of the legrest 25 in the front-rear direction is limited. For this reason, for example, as shown in FIG. 8, the corner of the front end of the leg portion 25 ^ abuts on a part 41 of the lower part of the user's knee (eg, the belly), and the user may feel pain. . Therefore, there is a demand for a massage chair that can further improve the user's comfort. The present invention has been accomplished by focusing on the conventional problems, and its object is to provide a massager that can improve the user's comfort. (Means for solving the problem) The massager of the present invention includes: a seat for the user to sit down; and the upper part of the upper part of the lower part of the knee which is installed in front of the seat and can support the user is slightly flat 200524573 And the first surface is a concave-convex shape including a concave portion and a convex portion, and the second surface is a slightly flat shape, and the front end of the knee support portion is rotatably mounted as a rotating shaft. The surface becomes the upper surface to support the user's knee in the recessed portion. When turning to the front-side direction, the second surface becomes the upper surface and forms a slightly flat surface together with the upper surface of the lower knee support portion * to support the above. It is composed of a massage device under the user's knee. With this configuration, when the user receives a massage, the massage device is turned to the rear side, and the first surface of the concave-convex shape becomes the upper surface, so that the user's knee is supported by the concave portion of the massage device. On the other hand, when the user does not receive a massage, the massage apparatus turns to the front, the slightly flat second surface becomes the upper surface and forms a slightly flat surface together with the upper surface of the knee support portion. The lower part of the knee is supported by the support part and is supported by the massage device. In addition, the massager of the present invention may be configured to be disposed in front of the knee support portion, to support the lower part of the user's knee when the massage device is turned to the rear, and to support the user when the massage device is turned to the front, ^ Supporting part to support the massage device. According to this configuration, the user can support the lower part of the user's knee even when the massage device is turned to the rear, and at the same time, when the massage device is turned to the front, even when the force transmitted to the massage device is large under the user's knee, The support portion can still fully support the massage device and further support the user's knee. In addition, the massager of the present invention may have the following configuration. The upper surface of the support portion has a concave-convex shape that fits into the first surface of the massage device. According to this configuration, when the massage device is turned to the rear, the -7-200524573 convex portion on the support portion can support the lower part of the user's knee, and when the massage device is turned to the front, the support portion can restrict the movement of the massage device. . In addition, the massager of the present invention may have the following configuration. When the massage device is turned to the rear, the lower portion of the concave portion on the first surface of the massage device and the upper portion of the convex portion on the upper surface of the support portion form a slightly flat surface. According to this configuration, when the user receives a massage, the upper lower knee portion and the lower lower knee portion are supported by substantially the same surface. -In addition, the massager of this invention can be comprised as follows. When the massage device is turned to the rear, the lower portion of the concave portion of the first surface of the massage device and the upper surface of the support portion form a slightly flat surface. According to this configuration, when the user receives a massage, the upper lower knee portion and the lower lower knee portion are supported by substantially the same surface. (Effects of the Invention) According to the present invention, when the user receives a massage, the massage device is turned to the rear, the first surface of the uneven shape becomes the upper surface, and the user's knee is supported by the massage device. On the one hand, when the user does not receive a massage, he or she presses the ® device to turn forward, and the slightly flat second surface becomes the upper surface and the upper surface of the knee support portion forms a slightly flat surface. The lower knee support portion is supported, and the lower knee portion is supported by the massage device, so the user's comfort can be improved. [Embodiment] Hereinafter, a massager according to an embodiment of the present invention will be described with reference to the drawings. First, a first embodiment of the present invention will be described. Figures 1 and 2 show the external view of a massage chair according to the first embodiment of the present invention. The massage chair 100 shown in Figs. 1 and 2 200524573 includes a chair body 106, a leg portion 108, a knee support portion 110, a support portion 116, and a massage device 122. The chair body 106 is composed of a seat portion 102 and a backrest portion 104. The chair body 106 is supported by the legs 108. The lower knee support section 110 is mounted in front of the seat section 102. The upper surface of the lower knee support 11 is a slightly flat surface and can support the upper part of the lower knee of the massage chair 100 (for example, from the vicinity of the knee to the vicinity of the leg and belly). The support portion 116 is formed in front of and below the knee support portion 110. An upper surface of the support portion 116 is formed in a concave-convex shape having two wall portions # 1 1 2 extending in the front-rear direction and a groove portion 14 formed between the two wall portions 1 12. In the massage chair 100 shown in Figs. 1 and 2, although the knee support portion no and the support portion 116 are integrally formed, the knee support portion 110 and the support portion 1 16 may be separate entities. The massaging device 122 is rotatably mounted on a pivot shaft 124 which is formed by extending left and right at the front end of the lower knee support portion 110 as a rotating shaft. One side of the massager 122 has three wall portions 118 formed at the left and right ends and the central portion, and two groove portions 120 formed between the three wall portions 118, and is formed in an uneven shape. ^ In contrast, the other surface of the massage device 122 is formed as a slightly flat surface. A mechanism (not shown) for realizing the massage function is formed inside the wall portion 118. When the massage device 122 is turned to the rear (toward the vicinity of the chair body 106) with the pivot 124 as the rotation axis, as shown in FIG. The flat surface becomes the lower surface and is supported by the lower knee support portion H0. When the user arranges the massage device 122 as shown in FIG. 1, the user lies on the chair body 106 and lays each 200524573 feet in two grooves 120, and the upper part of the knee is supported by the massage device 122. The lower part of the knee is supported by the wall part 1 1 2 of the support part 1 1 6 (for example, the part from the vicinity of the leg to the ankle), and the upper part of the knee can be massaged. In addition, the user can shift the body toward the upper side of the chair body 106 to receive a massage to the lower part of the knee by the massage device 122. In addition, it is also possible to receive a massage of the upper part of the lower knee with the massager 122 while lying down on the chair body 106 and a massage of the lower part of the lower knee with the massager 122 while lying down. ， Form a chair body 106. • In the case where the massage device 122 is arranged as shown in Fig. 1, it is preferable that the bottom of the recessed portion of the groove portion 120 of the massage device 122 and the upper portion of the wall portion 112 of the support portion 116 are formed into a flat surface. With this, when the user accepts the friction, the upper part of the lower knee and the lower part of the knee are supported by substantially the same surface, which can improve the comfort. On the other hand, when the massage device 122 is turned to the front (toward the direction away from the chair body 106) with the pivot 124 as the rotation axis, as shown in FIG. The face of the shape becomes ^ below. In this case, a slightly flat surface is formed from the upper surface of the lower knee support portion 110 and the slightly flat surface of the massager 122. Then, after the user who has not received a massage lies down on the chair body 106, the upper part of the lower knee is supported by the lower knee support part 110 by stretching the feet, and the lower part of the knee is supported by the massage device 122. Thereby, since most of the user's knee is supported, the comfort can be improved. When the massage device 1 22 is arranged as shown in FIG. 2, the uneven surface of the wall portion 118 and the groove portion 120 of the massage device 122 and the wall portion 112 and the groove portion 114 of the support portion 116 are formed. The concave and convex shape faces and fits -10- 200524573. With this, even when the force transmitted to the massage device under the user's knee is large, the support portion 116 can still support the massage device 122 and further fully support the user's knee. In addition, the 'massage device 122 and the support portion 116 are concave-convex shape and fit each other. Therefore, the support portion 1 1 6 can restrict the movement of the massage device ^ 122 and increase the sense of stability. Λ Next, a second embodiment of the present invention will be described. 3 and 4 are external views of a massage chair according to a second embodiment of the present invention. In Figs. 3 and 4, the massage chair 200 shown includes a chair body 206, a foot portion 208, a knee support portion φ210, a support portion 216, and a massage device 222. The chair body 206 has the same structure as the chair body 106 of the first embodiment shown in Figs. 1 and 2, is composed of a seat portion 202 and a backrest portion 204, and is supported by a leg portion 208. The under-knee support 210 is the same as the under-knee support 110 of the first embodiment shown in Figs. 1 and 2. It is installed in front of the seat 202 and has a slightly flat upper surface to support the user of the massage chair 2000. Upper knee.
