Explaining the conventional electric massager based on FIGS. 1 and 2, the casing 1 is composed of, for example, a lower casing 1a and an upper casing 1b, and a rotary drive mechanism such as an electric motor installed inside the casing 1 ( The rotary shaft 2 driven and rotated by (not shown) is inserted through the shaft hole 3 provided in the upper casing 1b and protrudes to the outside, and the rotary treatment body 4 is fixed to the insertion end portion of the rotary shaft 2. ..

Normally, as shown in FIG. 1, a cover sheet 5 made of a flexible sheet such as a woven fabric is attached to the casing 1. Therefore, the rotary treatment body 4 is covered with the cover sheet 5 and is rotated inside the cover sheet.

By the way, the cover sheet 5 is configured to be removable for the purpose of washing or the like, and can be easily removed by the user.

In this regard, the electric massager with the cover sheet 5 removed is not originally planned to be used, but it can be used as a massager as it is, so it is actually used by the user. May be done.

However, as shown in FIG. 2, the entire rotary treatment body 4 is arranged outside the upper casing 1b, and the rotation shaft 2 has a neck portion 2a to which the rotation treatment body 4 is fixed inserted from the shaft hole 3. Therefore, it is extremely dangerous to use the electric massager with the cover sheet 5 removed.

For example, if the user's clothes, accessories such as a necklace, hair, etc. come into contact with the rotating treatment body 4 or the neck portion 2a of the rotating shaft 2, the rotating treatment body 4 or the rotating shaft 2 may be wrapped around and strongly caught, which may lead to personal injury.

Therefore, it is desirable to provide an electric massager that does not pose the above-mentioned danger even if the user should use it with the cover sheet removed, and this point is an object of the present invention.

A protective cover means having an insertion hole having an inner peripheral edge facing the outer peripheral surface of the substrate is provided, and the outer peripheral surface on the base end side of the substrate is covered from the periphery by the protective cover means, and the flange is used to cover the outer peripheral surface of the substrate. The point is that the gap between the outer peripheral surface of the substrate and the inner peripheral edge of the insertion hole is covered from the inside of the protective covering means .

The protective cover means can be configured by the case wall of the casing, or can be configured by a plate member mounted on the casing.

According to the present invention, even if the electric massager from which the cover sheet 14 is removed is used by the user, there is no danger of foreign matter such as clothes or a necklace being caught. When a foreign substance comes into contact with the rotating treatment body 13, it easily moves toward the tip end along the tapered surface 15 of the substrate 16 and is released upward, so that it does not wind around the rotation treatment body 13. At this time, even if a thin foreign substance tries to enter the insertion hole 20, it is difficult to enter by bringing the inner peripheral edge 20a close to the tapered surface 15, and the foreign matter is moved along the tapered surface 15 and shaken off before entering. Therefore, there is an effect that the wrapping of foreign matter can be suitably prevented.

Since the flange 18 is provided on the base end side of the rotary treatment body 13, even if a thin foreign substance is about to enter the inside of the inner peripheral edge 20a of the insertion hole 20, the inner peripheral edge 20a and the tapered surface 15 Since the gap between them is covered from the inside of the protective cover means 19 by the flange 18, further entry is prevented and wrapping is surely prevented.
