DETAILED DESCRIPTION OF THE INVENTION

[0001]

[0002]

2. Description of the Related Art As a conventional hand-held type vibrating massager, there is known, for example, the one disclosed in Japanese Patent Application Laid-Open No. 63-51862. In this conventional example, the axial direction of the handle coincides with the axial direction of the eccentric weight. It is also known that bending the handle 1 itself as shown in FIG. 9 in that coincides with the axial direction of the axial and eccentric weight of the handle 1 to the L-shape. In FIG. 9 , reference numeral 4 denotes a vibrating head portion having an eccentric weight mounted therein.

[0003]

However, in the above-mentioned prior art, if the axis direction of the handle and the axis direction of the eccentric weight simply coincide, the circumferential direction of the vibrating head portion can be used, but the top surface portion cannot be used. There is a problem that the handle is difficult to handle and that the handle bent in an L-shape is necessarily large.

Conventionally, there has been no rotary head provided with a projection on a vibrating head, so that it cannot be used in various ways. Further, conventionally, the connecting spring portion is arranged in series between the vibration head portion and the handle portion, and a space for the connecting spring portion is required in design. Further, in the related art, there is no device in which a second vibration absorbing portion is provided between a handle portion and a vibrating head portion driven by vibration with an eccentric weight.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned problems of the prior art, and has as its main object to provide a massager in which the top surface of the vibrating head can be easily used. is there. Another object of the present invention is to provide a massager that can be used in a variety of ways, can effectively prevent transmission of vibration to the handle side, and can effectively perform manual tapping treatment.
