2. Description of the Related Art Conventionally, as a relaxation device, a massage chair for upper body massage including elimination of stiff shoulders has been known. This massage chair is designed to be able to hit the shoulder and to rub shoulders etc. by the operation of the roller, but the roller is built in the backrest part, and the roller is projected from the surface of the backrest part Not. For this reason, since the roller hits from behind the user in the sitting posture, the user's shoulder cannot be lifted from directly above, and the shoulder padding becomes insufficient.

Further, there is known a shoulder hitting chair in which a roller is projected from the surface of a backrest portion, and the roller is vibrated up and down to hit a shoulder. This shoulder tapping chair has a roller protruding from the surface of the backrest, so it can hit the user's shoulder from directly above, but it is only for shoulder tapping where the roller vibrates up and down and hits the shoulder. Therefore, there is no shoulder rubbing effect of applying vibration while applying weight to the shoulder.

When playing with a slot machine installed in a pachinko parlor or the like, a user inserts coins while sitting on a chair, and sequentially presses three buttons to stop a rotating drum. Since a monotonous operation of repeating the movement is repeated, stiff shoulder tends to occur easily. In order to eliminate such shoulder stiffness, it is preferable for a user to incorporate a shoulder rubbing device into a chair for a slot machine and to rub the shoulders while sitting in a seated posture while staying at the place. I can't find any kind of shoulder firs chair.

[0005]

According to the present invention, a shoulder fir can be formed from directly above a shoulder by applying vibration while applying weight to the shoulder while sitting on a chair, and can be used mainly as a chair for a slot machine.
