DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a gripping rod capable of gripping one end with a left or right hand, and a roller rotatably supported on the other end of the gripping rod. The present invention relates to an improvement of a massager which is capable of rolling while vibrating the roller in contact with a part of the body.

[0002]

2. Description of the Related Art Conventionally, such a massager is already known, for example, from Japanese Utility Model Laid-Open No. 2-15131.

[0003]

In the above-mentioned conventional massage device, the roller formed in a thick cylindrical shape is rotatably supported by a shaft provided on the gripping rod, and the heat capacity of the roller is large. In addition, since the inner periphery of the roller is in contact with the outer periphery of the shaft, heat transfer between the roller and the shaft is good. For this reason, when a cold roller is brought into contact with a part of the body, it takes time for the temperature of the roller to rise even by heat transfer due to contact with the body, and the user may feel uncomfortable forever. Further, the weight of the roller is relatively large due to the thickness, and the power required by the vibration generating means to vibrate the roller also increases.

The present invention has been made in view of such circumstances, and enables the temperature of the roller to be quickly increased by contact with the body, and reduces the power required to generate vibration. An object of the present invention is to provide a massager as described above.

[0005]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention provides a gripping rod capable of gripping one end with either the left or right hand, and another end of the gripping rod. A roller rotatably supported on the side, and a massager adapted to be able to roll while vibrating the roller in contact with a part of the body, at the other end of the gripping rod, A cylindrical roller support cylinder incorporating vibration generating means for vibrating the roller is provided, and both ends in the axial direction of the roller having a thin cylindrical portion coaxially surrounding the roller support cylinder are rotatable on the roller support cylinder. And an annular gap is formed between the thin cylindrical portion and the roller supporting cylinder.

According to such a configuration, since the roller has a thin cylindrical portion, the weight and heat capacity of the roller can be set relatively small, and the roller support cylinder and the roller supporting the roller can be set. By forming the annular gap therebetween, heat can be hardly transmitted from the roller to the roller support cylinder. For this reason, when the roller is brought into contact with a part of the body, the temperature of the roller can be quickly raised by heat transfer from the body, so that the user does not feel uncomfortable. In addition, since the roller is relatively lightweight, the power required by the vibration generating means housed in the roller support cylinder to vibrate the roller can be reduced.
