Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a massaging device for massaging a user by means of a pair of massaging rollers provided on a rotary drive shaft.

[0002]

2. Description of the Related Art There are various types of massaging devices, and one of them is known as the massaging device disclosed in Japanese Patent Publication No. 59-15652. In the massaging device disclosed in this publication, a pair of wheel bodies (massage rollers) are rotatably provided at a substantially central portion of a reciprocating main shaft with a predetermined size eccentric to the main shaft via an eccentric shaft. Has been.

Therefore, when the main shaft is driven to rotate, the wheel body moves eccentrically, so that the user's body can be massaged by the eccentric movement.
The pair of wheel bodies are provided with the same eccentric phase with respect to the main shaft. Therefore, since the pair of wheels press the user's body at the same time as the main shaft rotates, the pair of wheels can be used to push and massage the user's body, and the eccentricity allows the body to be massaged. As compared with the case where the user is not eccentric, the user can be masturbated more strongly.

By the way, when receiving a massage with such a massage device, a user may want to receive not only a push-up massage but also a hitting massage. However, if a pair of wheels are provided on the main shaft with the same phase of eccentricity, the pair of wheels press the user's body at the same time as described above. There was something I couldn't do.

[0005]

As described above, in the conventional massaging device, a pair of massaging jigs are attached to the main shaft.
Since the la is installed in the same eccentric state, there was a case where the user could push the user to perform massaging, but not hitting. An object of the present invention is to provide a massage device which allows a user to selectively perform a push-up massage and a tapping massage.

[0006]

According to a first aspect of the present invention, there is provided a drive shaft rotatably supported, at least a pair of mass gyroscopes eccentrically provided on the drive shaft, and the drive shaft. When the driving means for rotating and rotating in the reverse direction and the driving shaft is driven to rotate in a predetermined direction by the driving means, the eccentric phases of the pair of massaper rollers are made substantially the same, and the driving means is rotated in the reverse direction. And a phase control means for shifting the phase of the eccentricity by a predetermined angle.

According to a second aspect of the present invention, in the first aspect of the invention, the phase control means has an outer peripheral surface on which the mass gyro is attached.
And a second eccentric cam eccentrically mounted on the drive shaft and rotatably mounted on the drive shaft, and the drive shaft is rotated in a predetermined direction. The phase of the second eccentric cam is the same as the phase of the first eccentric cam when it is rotated, and when it is rotated in the reverse direction, the phase of the second eccentric cam is a predetermined angle with respect to the phase of the first eccentric cam. Angle setting means for setting a relative rotation angle of the second eccentric cam with respect to the drive shaft so as to be displaced.

According to a third aspect of the present invention, in the first aspect of the invention, the drive shaft is formed in a hollow shape, and the drive means is provided inside the drive shaft. According to the invention of claim 1, the phase of the eccentricity of the pair of massaji rollers can be set to the same state or a state shifted by a predetermined angle depending on the rotation direction of the drive shaft. If the eccentricity phases of the pair of massaging rollers are the same, it is possible to perform massaging by pushing the user, and if they are offset by a predetermined angle, it is possible to perform striking massaging.

According to the second aspect of the invention, one of the pair of eccentric cams is fixed to the drive shaft and the other is rotatably provided within a predetermined range with respect to the drive shaft, so that the other eccentric cam is driven. By rotating relative to the shaft, the phase of the eccentricity of the pair of eccentric cams can be selectively changed between the same state and the state in which the eccentricity is deviated by a predetermined angle, so that the phase control can be reliably performed with a simple configuration It becomes possible.
