The reason why the projecting length is set shorter is that, as described in the first embodiment, in general, the human body is curved forward with the shoulders on both sides with respect to the neck, so that the pressing position located inside is By making the length of the protrusion 32c shorter than that of the pressing protrusion 32b located on the outside, the pressing force is applied to the root and the shoulder of the neck by the pressing protrusion 32c and the pressing protrusion 32b, respectively, on average. is there.

A bag 33 is disposed between the rotating plate 138 and each of the pressing plates 32. The manner of attaching the bag 33 is the same as in the first embodiment. Therefore, the description is omitted. In addition, the bag 33
Is connected to an air distributor 41 via an air hose 33a as in the first embodiment.

When the air generated by the air compressor 40 is supplied to and exhausted from the bag 33 by the air distributor 41, as in the first embodiment,
As the bag body 33 expands and contracts, the pressing plate 32 rotates about the shaft portion 32a along with the expansion and contraction. With this rotation, the pressing projections 32b and 32c also rotate in the vertical direction, and the neck and the shoulder are rotated. Part will be pressed.

When the user does massage and the pressing projections 32b and 32c are not located at desired positions on the neck and shoulder due to his / her body shape, the movable plate 137 and the movable plate 138 are respectively moved. As described above, the positioning member 150 and the positioning member 138e are operated to adjust the moving plate 131 by moving the moving plate 131 in the lateral direction, and similarly, by rotating the rotating plate 137 to adjust the pressing protrusion. 32b and 32c are positioned at desired positions.

The operation of the chair type air massage machine of the second embodiment is the same as that of the first embodiment. In other words, in use, the user sits on the seat 2 with his / her back against the backrest 3, and also places the legs or calves on the leg rests 52a and 52b, and then puts the remote control device 46 on the leg rests 52a and 52b. Operate to select and set a desired massage mode from the various massage modes, and then operate the remote control device 46 to input an operation start signal to execute the selected massage mode and execute the desired massage. Is made.

When the massage mode of the neck / shoulder massage is set as the massage desired by the user, air is supplied to the bag body 33 of the neck / shoulder massage means 130 via the air distributor 41. The pressing plate 32 is rotated about the shaft portion 32a as a rotation axis by the bag body 33 which expands and contracts with the supply and exhaust of air,
With the rotation of the pressing plate 32, the neck and the shoulder are pressed downward from above by the pressing protrusions 32b and 32c to perform massage. And
Since the pressing projections 32b and 32c press the neck and the shoulder downward from above, the neck and the shoulder are not pushed forward in the process of being pressed by the pressing projections 32b and 32c, and are reliably pressed. , A good acupressure effect is obtained, and the pressing protrusion 32
Since b and 32c are positioned at the positions desired by the user, a good massage effect can be obtained.

In the second embodiment, each of the movable plates 137 is independently moved in the lateral direction independently of each other. The configuration may be such that both moving plates 137 can be moved simultaneously. However, when the two moving plates 137 are moved separately as in this embodiment, there is an advantage that fine adjustment can be performed even when the desired position is not symmetrical depending on the body shape or the like. Also, in the second embodiment, each pressing plate 32 is provided with two pressing projections 32b and 32c. However, as in the first embodiment, one or more pressing projections 32b and 32c are provided. The shape may be any shape.
