Further, since the movable support 52, which is a part of the support 51, is supported so as to be movable back and forth with respect to the bottom frame 40, the form of the plurality of supports 51 can be changed by moving the bottom frame 40. If the cover member 50 is loosened or stretched when the cover member 50 is changed, the movable support 52 and the bottom frame 40 can be displaced relative to each other in the front-rear direction X, and the support 51 and the bottom frame 40 can be displaced relative to each other. The positions of each other can be adjusted to positions where the cover member 50 is less likely to be burdened. As a result, deterioration of the cover member 50 is suppressed, and the appearance of the support base 11 is not impaired.

Further, since the regulating unit 60 is provided, the relative displacement in the left-right direction Y can be regulated while allowing the relative displacement of the movable support 52 and the bottom frame 40 in the front-rear direction X.
Further, since the regulating portion 60 includes the guide portion 61 and the guided portion 62, the relative displacement in the left-right direction Y is surely regulated while allowing the relative displacement of the movable support 52 and the bottom frame 40 in the front-rear direction X. Can be done.

Further, since the guide portion 61 and the guided portion 62 are composed of the elongated hole 63 and the shaft member 64, the guide portion 61 and the guided portion 62 are configured to employ, for example, two members that engage with each other. As compared with the above, the increase in the number of parts of the guide portion 61 and the guided portion 62 can be suppressed, and a simple configuration can be obtained.

Further, since the support base 11 for supporting the user and the stand 12 for supporting the support base 11 in a changeable manner are provided, and the support base 11 is supported by the support structure 70 of the support base described above, the support base 11 is supported. In the body support device 10, each of the above-mentioned effects can be exerted.

The technical scope of the present invention is not limited to the above-described embodiment, and various modifications can be made without departing from the spirit of the present invention.

For example, in the above embodiment, the support structure 70 of the support base includes a regulation unit 60 that allows the relative displacement of the movable support 52 and the bottom frame 40 in the front-rear direction X and regulates the relative displacement in the left-right direction Y. Although the configuration is shown, it is not limited to such an aspect. The support structure 70 of the support base does not have to include the regulation unit 60.

Further, in the above embodiment, the regulating portion 60 is disposed on the guide portion 61 disposed on one of the support 51 and the bottom frame 40, and on one of the guide portions 61, and is arranged in the front-rear direction by the guide portion 61. Although the configuration including the guided portion 62 guided by the X is shown, the present invention is not limited to such an embodiment. The regulating unit 60 does not have to include the guide unit 61 and the guided unit 62.

Further, in the above embodiment, the guide portion 61 is an elongated hole 63 that opens toward either the upper side or the lower side and extends along the front-rear direction X, and the guided portion 62 is the elongated hole. Although the configuration is shown in which the shaft member 64 is inserted in the vertical direction Z in the 63, the present invention is not limited to such a mode. The guide portion 61 and the guided portion 62 may have a configuration other than the elongated hole 63 and the shaft member 64, such as the rail member and the slide member constituting the slide rail.

In addition, it is possible to replace the components in the embodiment with well-known components as appropriate without departing from the spirit of the present invention, and the above-mentioned modifications may be appropriately combined.
