- the exhaust port 708 is arranged not directly above the roller 702, but diagonally above the roller 702. The distance to the outlet 708 is further lengthened to make it difficult for the lubricant to flow into the exhaust port 708 .
- the diameter of the roller in the portion where the distance between the exhaust port and the roller rotation axis is close is made smaller than the diameter of the roller in other portions.
- both may be used like Suction Cup-A701.
- the top plate 711 on which the exhaust port 708 is arranged flat like the suction cup-A701 the top plate has a concave portion recessed in the direction opposite to the roller, and the concave portion is provided with the exhaust port. It is also effective to lengthen the distance between the roller and the exhaust port, and it is more desirable to place the exhaust port obliquely above the roller and to reduce the diameter of the roller near the exhaust port.
- the roller 702 described above has a configuration in which the diameter of the center portion is small
- the configuration is not limited to this, and for example, a configuration in which the diameter of only one end portion is small may be employed.
- the exhaust port may be provided above the portion where the diameter is reduced, and the exhaust port may be arranged obliquely above the portion where the diameter is reduced instead of directly above the portion where the diameter is reduced.
- the shape of the roller 702 and the positional relationship between the roller 702 and the exhaust port 708 prevent the lubricant accumulated in the cup 705 from flowing into or being sucked into the exhaust port 708.
- a filter that allows air to pass through but not lubricant may be placed in exhaust port 708 . If a large amount of lubricant is sucked into the exhaust port 708 at one time or if the lubricant flows in frequently, the filter will quickly become clogged, preventing the lubricant from flowing into the exhaust port 708. In general, countermeasures cannot be expected to be very effective.
- the electric signal output from the body part 11 is supplied to the affected part by the electrode part-A703 and the electrode part-B704.
- the electrical signal used may be the electrical signal described using FIGS. 2 to 9, or may be a high frequency or radio wave of several kilohertz or higher. Alternatively, it may be a low-frequency signal of about several tens of Hz, such as a pulse used in TENS (transcutaneous electrical stimulation therapy).

- the two electrodes, electrode part-A703 and electrode part-B704, are arranged so that the current flowing through these two electrodes is parallel to the rotation axis of the roller 702, but this is not the only option.
- the electrodes may be arranged so that the current flows in the direction perpendicular to the rotation axis of the roller 702 .
- the suction cup A701 uses a suction pump to create a negative pressure in the cup 705.
- the blow-out type suction cup is of a type in which the air in the cup 705 is sucked out by applying Bernoulli's theorem by sending air into the suction cup with a blow-out pump.
- a hose used for a suction pump needs a certain amount of strength so that the hose will not be crushed or bent due to the negative pressure inside the hose due to suction, and it tends to be a hard and heavy hose.
- the suction cup needs to be provided with an outlet through which the air sent into the suction cup and the air in the cup 705 are discharged. is clogged.
