DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electric razor in which an outer cutter frame for holding an outer cutter is mounted on a razor body so as to float.

[0002]

2. Description of the Related Art As shown in FIGS. 17 and 18, an electric razor in which an outer cutter frame 2 for holding an outer cutter 1 is mounted on a razor body 3 so as to float freely is known. In this case, the outer blade frame 6 is attached to the end of the razor body 3.
The outer cutter case 11 is removably attached to the outer cutter frame 6, and the outer cutter frame 2 is attached and held by the outer cutter case 11 so as to elastically urge the outer cutter frame 2 outward. . Therefore, in this case, the outer blade frame 2 is resiliently urged outward to be able to float freely, and the outer blade 1 is adapted to the skin and a good shaving effect can be obtained. However, in this case, the float operation of the outer cutter frame 2 is difficult to be seen from the outside because the outer cutter frame 2 enters the outer cutter case 11 in a floating state, and the outer cutter 1 follows the skin during shaving. There is a problem that it is difficult to actually detect whether or not it is operating.

[0003]

In order to solve the above-mentioned problems, the outer blade case 11 covering the outer blade frame 2 is removed, or the outer blade frame 2 is replaced with the outer blade case 11. Can be dealt with depending on whether it is arranged outside the. If the outer cutter case 11 is removed, there is a disadvantage that the outer cutter frame 2 cannot be attached and held so as to elastically urge the outer cutter frame 2 outward. Placement on the outside is considered an appropriate countermeasure. As described above, when the outer cutter frame 2 is arranged outside the outer cutter case 11, the float operation of the outer cutter frame 2 can be visually detected and realized.

However, in this case, since an external force is easily applied to the outer cutter frame 2 on the outer side, a force for easily floating the outer cutter frame 2 from the outside easily acts. Therefore,
Even when the blade protection cap is provided, the outer blade frame 2 is floated together with the blade protection cap.
When an external force is applied during storage in a soft case or the like, a force is constantly applied to a spring member for giving a resilient force to the outer blade frame 2 to be floated, and the spring member is twisted or deformed. And adversely affect the characteristics of the float operation during actual use.

[0005] The present invention has been invented in order to solve all of the problems in the above-mentioned conventional technology, that is, the problem is that the float operation of the outer cutter frame can be easily visually detected when viewed from the outside, and moreover, Another object of the present invention is to provide an electric shaver which can easily prevent a float operation of the outer cutter frame when not in use and maintain its characteristics in a good condition.
