Abstract: A chair-type massage machine has a seat, a backrest part, and a treatment mechanism that is provided in the backrest part so as to able to move up and down, and the treatment mechanism comprises: a treatment arm having a treatment element at substantially a tip end thereof; a massage power selection mechanism for adjusting massage strength by displacing the treatment arm between a weak state in which the treatment arm is substantially parallel to a backrest face of the backrest part and a strong state in which the treatment arm is erected substantially perpendicular to the backrest face; and a push-out member that is provided closer to a base end side than the treatment element of the treatment arm and is positioned below the treatment element when the treatment arm is in the strong state.

Abstract: A massage machine comprises a drive shaft rotatably driven in forward and reverse directions; a pair of inclined shafts mounted on both ends of the drive shaft so as to have an arbitrary inclination relative to an axial direction of the drive shaft; a pair of left and right massage ball units including massage balls and rotatably connected to outer peripheral surfaces of the pair of inclined shafts, respectively; and switching means for switching an axial rotation position of one inclined shaft of the pair of inclined shafts. The massage ball units each comprise a swing arm having one end rotatably connected to the outer peripheral surface of the inclined shaft; and a support arm connected to the other end of the swing arm and having mounted thereon multiple massage balls at a vertical distance from each other.

Abstract: A massage chair has a seating surface, a backrest and armrests at the opposite left and right sides. A covering member vertically displaceable to be opened and closed is provided on the upper surface of an armrest main body of each armrest. A massaging device is provided on at least either one of the lower surface of each covering member and the upper surface of the corresponding armrest main body. The massaging devices are driven with hands and arms tightly held between the lower surfaces of the covering members and the upper surfaces of the armrest main bodies, and the upper surfaces of the covering member serve as arm resting surfaces with the covering members closed and the massaging means not driven. There can be provided a massage chair whose arm resting positions are not restricted when the massage chair is not used to massage the hands and arms.

Abstract: This massage machine comprises a seat 20, a leg-rest 50, a footrest 60, an electric extendable mechanism 80, a link mechanism 70, and a controller. The footrest is movably linked to a lower end of the leg-rest to be movable relative to the leg-rest, and is provided with air bags 63 configured to restrain a foot of the user. The electric extendable mechanism and the link mechanism are configured to move the footrest relative to the leg-rest. The controller gives the user a leg stretching mode, and in the leg stretching mode, the controller controls the electric extendable mechanism and the air bags such that the electric extendable mechanism moves the footrest relative to the leg-rest while the air bags restrains the foot of the user.

Abstract: In a massager having a pair of medical treating members, a distance between the medical treating in medical treatment such as tapping or backstretch, except massaging can be varied corresponding to rotation angle of a driving shaft. A distance detector comprises a rotation disc rotated with the rotation of the driving shaft and having at least two apertures formed along the same circle, and an optical detector for detecting edged of the apertures in circumferential direction of the rotation disc. At least three edges of the aperture are homologized to at least three stages of the distances between the medical treating members, so that the distances between the medical treating members can be adjusted by monitoring output signal of the optical detectors.
