Preferably, the substantially 8-character shape is a ratio of the length Wxa in the longitudinal direction of 1 to 2 when the width Hya in the short-side direction of the 8 character is 1. In addition, since the adaptation size of these actual dimensions is due to the physique difference by race, the physique difference by adults, infants, etc., it is preferable to design the one corresponding to the target layer of the hip joint exercise assisting device 1A based on these ratios ·To manufacture.

  For example, referring to the statistical data of Japanese physical characteristics, the average shoulder width of adults (male) is around 40 cm, and the female: around 36 cm, 50% of shoulder width x 1.4 to 2 times When the dimension including the calculated value is used as a guideline, for example, when targeting adult men and women in the domestic market as a target for mass production as a product, the width Wxa in the longitudinal direction is preferably 0.2 m to 0.5 m. It is formed in the range.

  Preferably, when the pedestal 2A is placed on a flat ground, the height of the foot 51 placed on the footrest 3A is in the range of 2 cm to 15 cm. This lower limit of the height is considered from the necessity of maintaining the structural surface such as the storage space for the footrest 3A and the rolling portion 4A and the strength surface such as the plate thickness. The upper limit of the height is because it is necessary to avoid that the knee of the foot 51 placed on the footrest board 3A is bent too much during the user's exercise.

  The hip joint exercise assisting device 1A as described above has an approximately 8-shaped horizontal and vertical length based on characteristics such as shoulder width and foot width on the human body, and is configured with an unreasonable ratio. Since it can be configured with a length that is not, it is possible to perform hip joint movement without placing an excessive burden on the body.

  The hip joint exercise assisting device 1A does not require any other power by the user's own power. In addition, it can be used regardless of age or sex because it can be exercised in a comfortable posture and is easy to handle.

  The hip joint exercise assisting instrument 1A can be used for both the left and right legs. Further, the user not only uses the hip joint exercise assisting device 1A by placing the longitudinal direction (width Wxa) in the direction along the shoulder width of the person but also, for example, in the short direction in the direction along the shoulder width of the person. (Hya) can be placed and used, and the direction can be tilted.

  The constituent material of the hip joint exercise assisting device 1A may be made of synthetic resin, wood, metal, or a combination thereof. Preferably, it is made of a synthetic resin such as plastic. Accordingly, the hip exercise assisting device 1A that is small, light, and sturdy is possible.

  The footrest 3D is movably disposed on the guide 20d. In the footrest 3D shown in FIG. 16, the lower surface is connected to one of the support rods 31d fitted into the guide 20d, and is positioned so as to provide a gap with the base 2D. Further, the upper surface has an area for placing one of the user's feet 51 (from heel to toe).

  The footrest board 3D includes a board 311d, a friction sheet 312d, and an anti-slip 313d.

  The board 311d has a thickness that allows the user to touch the sole of one foot (one foot 51) and put the foot on the one foot with some force. Preferably, the board 311d is provided with a non-slip 313d that eliminates the slipping of one of the user's soles.

  The friction sheet 312d is joined to the lower surface side of the board 311d. The friction sheet 312d is a sheet material that generates a frictional force with the sphere 41d, such as a rubber sheet.

  The support bar 31d is formed in a bar shape. In the support bar 31d, as shown in FIG. 16, one of the rod-like longitudinal directions is connected to the substantially central portion of the footrest 3D, and the other is connected to the track slip stopper 32d.

  The rod-like outer diameter of the support rod 31d is made smaller than the width of the groove of the guide 20d (the track interval between the outer guide 21d and the inner guide 22d). Further, the length of the rod-like longitudinal direction is larger than the sum of the thickness in the height direction (vertical direction) of the rail 40d and the height of the exposed portion of the sphere 41d, and the track slip-off stopper 32d has a floor on the lower side of the base 2D. It is made smaller than the length that does not contact the surface.

  The track slip-off stopper 32d has a shape capable of locking the rail 40d so that the footrest 3D is not pulled out from the rail 40d provided on the guide 20d.
