By combining the region changing mechanism and the swing interval expanding mechanism, the foot swing range becomes larger, and the contact between the fingertip of the left foot and the fingertip of the right foot is less likely to occur.

  (A) The leg support portion 16 has a structure shown in FIG. 52A as a swinging interval enlarging mechanism. That is, the airbag 53 of the leg back wall 41 of the leg support portion 16 has a structure in which only the portion on the leg side wall 42 side is fixed to the leg back wall 41. According to this configuration, contact between feet is suppressed as follows.

  As shown in FIG. 52 (b), when air is supplied to each airbag 53, a portion on the leg central wall 43 side of each airbag 53 is a leg with a portion on the leg side wall 42 side of the airbag 53 as a fulcrum. It is lifted towards R. As a result, the inner side of the left leg and the inner side of the right leg are lifted by the corresponding airbag 53, and the fingertip of the left foot and the fingertip of the right foot are inclined outward. That is, the interval between the fingertip of the left foot and the fingertip of the right foot is widened. This makes it difficult for the left foot and the right foot to come into contact with each other when the foot is swinging.

  (B) The leg support portion 16 has a structure shown in FIG. 53A as a swing interval expansion mechanism. That is, each leg back wall 41 is configured to be inclined with respect to the leg side wall 42 and the leg center wall 43 so that the part on the leg center wall 43 side is closer to the leg R than the part on the leg side wall 42 side.

  Specifically, a rotation shaft portion 391 provided at the left end of the left leg back wall 41, a rotation shaft portion 391 provided at the right end of the right leg back wall 41, and each rotation shaft. A drive mechanism 390 for rotating the portion 391 is added to the leg support portion 16. As the drive mechanism 390 and the rotating shaft part 391, the thing according to the structure of the driving mechanism 100 and the rotating shaft part 101 of 6th Embodiment is used. According to this configuration, contact between feet is suppressed as follows.

  As shown in FIG. 53 (b), when each leg back wall 41 is tilted with respect to the leg side wall 42 and the leg center wall 43, the inner side of the left leg and the inner side of the right leg correspond respectively. Therefore, the fingertip of the left foot and the fingertip of the right foot are each inclined outward. That is, the interval between the fingertip of the left foot and the fingertip of the right foot is widened. This makes it difficult for the left foot and the right foot to come into contact with each other when the foot is swinging.

  (C) The leg support 16 has a structure shown in FIG. 54 as a swinging interval enlarging mechanism. That is, each leg back wall 41 has a structure that is inclined with respect to the leg side wall 42 and the leg center wall 43 so that the part on the leg center wall 43 side is closer to the leg R than the part on the leg side wall 42 side. Each leg back wall 41 gives the left leg R the force with which the fingertip of the left foot tilts to the left. Further, the right leg R is imparted with a force to tilt the fingertip of the right foot to the right.

  (D) The leg support 16 has a structure shown in FIG. 55 as a swinging interval enlarging mechanism. That is, the left leg side wall 42 has a structure that inclines to the left as it goes forward. The right leg side wall 42 has a structure that inclines rightward toward the front. As described above, the leg support portion 16 has a left leg side wall 42 and a right side toward the distal end portion that is the front end portion of the leg support portion 16 from the proximal end portion that is the rear end portion of the leg support portion 16. The leg side wall 42 has a structure with a large distance in the left-right direction Y.

  According to the configuration of the leg support portions 16 of (C) and (D) above, the distance between the fingertip of the left foot and the fingertip of the right foot can be increased when the ottoman 12 does not swing. For this reason, when the ottoman 12 swings, the fingertips of the left foot and the right foot are prevented from contacting each other. Furthermore, since it is not necessary to use an actuator for moving the leg side wall 42 and an actuator for moving the leg back wall 41, the ottoman 12 is reduced in weight. For this reason, when the output of the actuator is the same, it is possible to suppress the range of the swing speed and swing width of the ottoman 12 by the swing mechanism from being reduced. Therefore, a more effective rocking feeling can be given to the user.

  (E) The leg support portion 16 has a structure shown in FIG. 56A as a swinging interval enlarging mechanism. That is, the leg center wall 43 has a left leg center wall 43A facing the left leg and a right leg center wall 43B facing the right leg. The leg central wall 43 has a space S between the left leg central wall 43A and the right leg central wall 43B in the left-right direction Y.

  According to this configuration, the distance between the left leg accommodating space 44 and the right leg accommodating space 44 is greater than that of the leg support 16 of each of the above embodiments. Thereby, the space | interval of a left leg and a right leg becomes large. For this reason, it is possible to increase the distance between the fingertip of the left foot and the fingertip of the right foot. This makes it difficult for the left foot and the right foot to come into contact with each other when the foot is swinging. Further, since it is not necessary to use an actuator for moving the leg center walls 43A and 43B, the ottoman 12 is reduced in weight. For this reason, there exists an effect similar to the leg support part 16 of said (C) and (D).

  -In the leg support part 16 of the modification of said (D), the actuator for moving each leg side wall 42 to the ottoman 12 can also be added. The actuator includes a rotating shaft portion whose center is the rear end of each leg side wall 42 and an electric motor that rotates the rotating shaft portion. The ottoman 12 has the following first usage pattern and second usage pattern as usage patterns of the leg support 16 that can be selected by the actuator. In the first usage pattern, as shown in FIG. 2, the leg side wall 42 is positioned along the front-rear direction X. As shown in FIG. 55 (b), the second usage pattern is a distal end portion that is a rear end portion of the leg side wall 42 and a front end portion of the leg side wall 42 with respect to the first usage pattern. The distance in the left-right direction Y between the left leg side wall 42 and the right leg side wall 42 increases.

In the leg support portion 16 of the modified example of (E), as shown in FIG. 56B, the leg back wall 41 is separated into the left leg back wall 41A and the right leg back wall 41B. You can also.
-In the leg support part 16 of the modified example of the above (E), an actuator for moving the leg center walls 43A, 43B to the ottoman 12 can be added. The actuator includes an electric motor and a reciprocating mechanism that converts the rotation of the electric motor into a reciprocating motion in the left-right direction Y. Each leg center wall 43A, 43B moves to the left-right direction Y with the reciprocating motion by a reciprocating mechanism. The ottoman 12 has the following first usage pattern and second usage pattern as usage patterns of the leg support 16 that can be selected by the actuator. In the first usage pattern, the distance between the leg center walls 43A and 43B in the left-right direction Y is relatively small. In the second usage pattern, as shown in FIG. 56, the distance between the leg center walls 43A and 43B in the left-right direction Y is relatively large.

-The modification of said (A), (B), and (D) can also be applied to the foot support part 17. FIG.
The modified examples (A) to (E) can be combined with each other.

In the modified examples (A) to (E), one of the part corresponding to the right leg R and the part corresponding to the left leg R in the leg support 16 may be omitted.
-In the ottoman 12 of each said embodiment, the rocking | interval expansion | swelling expansion mechanism shown to Fig.57 (a) can also be added. That is, the ottoman 12 has a left leg support 16A and a foot support 17A, and a right leg support 16B and a foot support 17B. The left leg support portion 16A and the left foot support portion 17A are inclined from right to left as they go downward from above. Further, the right leg support portion 16B and the right foot support portion 17B are inclined from the left side to the right side from the upper side to the lower side.

  According to this configuration, the distance between the left foot storage space 48 and the right foot storage space 48 of the foot support portion 17 is the same as that of the left foot storage space 48 and the right foot storage space 48 of each embodiment. It is larger than the distance from the foot accommodating space 48. For this reason, it is possible to increase the distance between the fingertip of the left foot and the fingertip of the right foot. This makes it difficult for the left and right fingertips to come into contact with each other when the foot is swinging.

  -It can replace with the ottoman 12 (refer FIG. 57 (a)) of the said modification, and can also provide the ottoman 12 shown by FIG.57 (b). The ottoman 12 has a central wall 43C corresponding to a portion in which each leg central wall 43 and each leg central wall 47 of FIG.

  -In the ottoman 12 (refer FIG. 57) of the said modification, the structure of the said leg support part 16 of the said (A)-(E) shown by FIGS. 52-56 can also be combined.
