2. Description of the Related Art As a massage machine having a simple structure mainly used at home, for example, as disclosed in Japanese Utility Model Publication No. 7-49943 (A61H 15/00), a rotation driven by a motor is used. A massage machine (roller massager) in which various treatment rollers are attached to a shaft is widely used.

The treatment roller attached to the rotary shaft is, for example, a finger pressure roller having a large number of finger pressure protrusions on a cylindrical support cylinder that rotates together with the rotary shaft, and a tilt roller in a direction opposite to the rotary shaft. There is a pair of rubbing rollers, etc., which are rotatably attached to the pair of attached rubbing bases each having a disk shape and provided with rubbing protrusions on the surfaces facing each other.

The acupressure roller presses a treatment area such as a sole or a calf on the rotation circumference of the acupressure projection which rotates together with a support cylinder, and applies cyclic acupressure stimulation to the treatment area by these acupressure projections. It is used. Further, the pair of rubbing rollers perform an operation of contacting and separating from each other according to the rotation of each of the rubbing bases accompanying the rotation of the rotating shaft, and the treatment site such as the sole of the foot or the calf located between these facing surfaces. It is used to stimulate by rubbing it from both sides.

[0005]

In the massage machine as described above, the rotating shaft is laterally supported by a synthetic resin outer case, and one end of the rotating shaft is supported for rotation drive in the outer case. The drive unit is connected to the motor and the rotary shaft is driven to rotate by the motor, so that the finger pressure roller and the rubbing roller perform a predetermined operation.

The outer case has a structure that can be vertically divided into a lower case (first case) and an upper case (second case), and a rotating shaft is laterally supported by the lower case and is supported in the lower case. After the drive unit is connected to the motor, the upper case is covered on the upper part of the lower case so as to be integrated, thereby facilitating the assembly.

On the other hand, since this type of massage machine is used by being placed on the floor surface, an operation board for performing operations including rotation, stop and speed adjustment of the drive section is generally a general one. It is mounted on the upper case so that it can be operated from the outside.

Therefore, when assembling the massage machine as described above, the operation board attached to the upper case and the drive unit assembled as described above inside the lower case are relayed including the operation signal cable, the power cable and the like. It is necessary to connect with a harness and to integrate the lower case and the upper case in this state. At this time, the relay harness is attached to the protruding parts such as fixing bosses and reinforcing ribs provided on the upper and lower cases. There is a problem that it takes a lot of time and effort to handle the relay harness so that the relay harness is not caught and broken.

Such a problem is not limited to the above-mentioned massage machine, but includes an outer case divided into a first case and a second case, a drive section is provided in the first case, and an operation board is provided in the second case. This is a problem that commonly occurs when assembling electric devices that are configured to include the above.

The present invention has been made in view of the above circumstances, and an operating board in which the first case and the second case are integrated and the driving portion supported in the first case and the second case are attached. It is an object of the present invention to provide an electric device that can be easily implemented without consideration of the handling of a relay harness that connects to and that can be assembled with high efficiency without fear of disconnection of the relay harness.
