Next, the operation of the aforementioned massage machine will be described.
First, when the motor 18 is driven to rotate, one gear 10 is rotated via the gear mechanism 20, and the other gear 12 is rotated in the opposite direction. Due to the rotation of both gears 10 and 12, both eccentric cams 14 and 16 are also rotated around the support shafts 6 and 8, and both lower sides are interposed via cylindrical portions 30 and 62 engaged with the eccentric cams 14 and 16. The movable tables 22b and 24b perform a circular motion.

  At that time, the rotation of the lower movable bases 22b and 24b is restricted by the restriction rods 31a and 31b. That is, with the circular movement of both lower moving bases 22b and 24b, the other lower moving base 24b slides along the regulating rods 31a and 31b, but the rotation of both lower moving bases 22b and 24b is restricted. .

  Along with the circular movement of the lower moving bases 22b and 24b, both the adjusting bases 32 and 64, the sliding shafts 46 and 66, and the acupressure elements 50 and 70 also make a circular movement. A comfortable massage can be received by placing the massage machine against the back of the chair or placing it on the floor and applying the acupressure elements 50, 70 to the affected area of the back.

  The two finger depressors 50 and 70 are circularly moved in opposite directions, and the urging members 56 and 72 are elastically deformed according to the pressing force acting on the finger depressors 50 and 70, so that the sliding shafts 46 and 66 are cylindrical portions. It slides in 44 and descends with the acupressure elements 50 and 70 in contact with the affected area. When the pressing force becomes weak, the acupressure members 50 and 70 are raised in a state where they are in contact with the affected area due to the elastic force of the urging members 56 and 72.

  Accordingly, the acupressure elements 50 and 70 move in a circular motion and move up and down to perform a three-dimensional motion. Therefore, the acupressure members 50 and 70 are complicated and can receive a comfortable massage without being habituated to a simple exercise massage.

  Further, the massage machine integrally forms the eccentric cams 14 and 16 on the gears 10 and 12, supports the moving bases 22 and 24 slidably on the flat portion 4 a of the upper case 4, and moves the moving bases 22 and 24. Engaging with the eccentric cams 14 and 16 and providing the finger depressors 50 and 70 on the movable bases 22 and 24, they can be formed in a flat shape, and the height from the bottom surface of the case 1 to the tips of the finger depressors 50 and 70 is high. Even if you use the massage machine standing on the back of the chair, you can sit comfortably on the chair and receive a comfortable massage. You can receive a comfortable massage without bowing.

  Since the adjustment mechanism 42 is provided, the locking claw 36 is slid, the tip is pulled out from the through hole 40, the adjustment bases 32 and 64 are moved along the groove 34, and the tip of the locking claw 36 is again moved. By inserting it into the through-hole 40, the distance between the two finger depressors 50 and 70 can be adjusted. Therefore, it can be adjusted to an interval suitable for the affected area of the user, and a comfortable massage can be received.
