  However, in the massage machine disclosed in the above publication, when the user is seated on the massage machine, the forearm is inserted into the holding wall provided at the top of the armrest, Because the retaining wall cannot be removed from the armrest, the massage machine is simply used as an easy chair or when the massage machine is used without the treatment of the forearm such as treating a body part other than the forearm In addition, the user needs to insert the forearm into the arm holder.

  In this way, when the forearm is inserted into the arm holder, the posture of the user is restrained, and even if the user wants to take another posture, the arm holder is obstructed and the user is It was difficult to take a desired posture.

The present invention has been made in view of such circumstances, and it is possible to treat the forearm of the user when necessary, and when the forearm is not treated, there is no part to interfere with every other arm, an object of the present invention is to provide a chair-type massage equipment that can be treated person to take a free attitude.

In order to solve the above problems, a chair-type massage apparatus according to the present invention includes an armrest portion that supports a forearm of a user , and can be attached to and detached from the armrest portion, and the forearm is sandwiched between the forearm of the user. A forearm massage device that applies pressure stimulation by an air bag to the chair-type massage device, wherein the armrest portion is a support portion that abuts and supports the forearm of the user with the forearm massage machine removed, and A fitting groove and a coupling socket for connecting an air pipe provided on the back side of the fitting groove, and the forearm massage machine includes a holding portion for holding a forearm of a user; A base that supports the clamping portion; a fitting protrusion that protrudes from the base and is fitted into the fitting groove; and is provided at a tip of the fitting protrusion in communication with the air bag. When the mating protrusion is fitted in the fitting groove Wherein said and a plug connected to the socket.
The fitting groove may be provided so as to extend laterally below the upper surface of the support portion, and the fitting protrusion may be fitted into the fitting groove from a side.

The chair-type massage device according to the present invention includes an armrest portion that supports a forearm of a user and a forearm massage that is attachable to and detachable from the armrest portion and that applies pressure stimulation to the forearm across the forearm of the user A chair-type massaging apparatus, wherein the armrest portion includes a support portion that abuts and supports the forearm of the user with the forearm massage machine removed, and a lower side than the upper surface of the support portion. The forearm massage machine is formed to protrude from the base, a holding part that holds the forearm of the user, a base that supports the holding part, and a fitting groove that extends in a direction. And a fitting projection that is fitted into the fitting groove from the side, and the clamping part is disposed above the support part with the forearm massage machine attached to the armrest part. It is characterized by that.

  In the present invention, since the forearm massage machine can be attached to and detached from the armrest, when treating the forearm of the user, the forearm massage machine is attached to the armrest and the forearm of the user is attached. When not treating, the forearm massage machine can be removed from the armrest, so that the user's forearm can be treated if necessary, and when the forearm is not treated, There is no part that obstructs arm placement at the top, so that the user can take a free posture.

  In addition, since the forearm massage machine sandwiches the forearm of the user, even if the forearm of the user is pressed, the forearm does not escape in the direction of the pressing, and the pressure stimulation by the forearm massage machine is ensured Can be given to the forearm of the user.

  Moreover, in the said invention, it is desirable for the said forearm massage machine to set it as the structure by which the length about the longitudinal direction of the said armrest part was made shorter than the length of the said armrest part. As a result, the forearm massage machine that is frequently attached and detached can be made small, and the treatment area by the forearm massage machine can be made relatively small, such as acupuncture points present in the forearm portion of the user It is possible to give a local pressure stimulus to a specific part of the skin and to further enhance the treatment effect.
