In the electric device of the present invention, the cap 7 covering the outer surface of the working head 3 is composed of an inner cap 7A covering the entire outer surface of the working head 3 and an outer cap 7B covering the outer surface of the inner cap 7A. Since the cap 7 is formed in a double cylindrical shape, the strength of the cap 7 is improved as compared with the case where the cap is formed by a single member. Inner cap 7 configured in a double cylindrical shape
When an external force acts on one of the caps A and the outer cap 7B, the caps 7A and 7B exert a reinforcing action to receive or disperse the external force acting on the other cap. Cap 7
This is because deformation and breakage of the can be prevented.

According to an electric device having an engagement structure for preventing the cap from coming off by engaging and engaging with each other on the engagement surface between the inner surface of the inner cap 7A and the mounting portion 17, for example,
When a drop impact acts on B, it is possible to prevent the cap 7 from easily coming off the mounting portion 17 of the case body 1. If the previous engaging portion is provided between the cap and the mounting portion of the conventional structure or between the outer cap and the mounting portion, the impact force acting on the cap or the outer cap is directly transmitted to the engaging portion. Therefore, the concave-convex engagement relationship in the engagement portion is easily released. In contrast, if an engagement structure is provided on the fitting surface between the inner surface of the inner cap 7A and the mounting portion 17, the impact force acting on the outer cap 7B is indirectly applied to the engagement structure via the inner cap 7A. The impact force is relaxed and absorbed during that time, and a part of the impact force is dispersed by the outer cap 7B, so that the cap 7 easily comes off from the mounting portion 17 easily. This is because it can be prevented.

When the inner cap 7A and the outer cap 7B are formed as a vertically-long, upwardly-shrinkable, sheath-like cap body having only one end opened, there is no waste in structural strength, and the overall rigidity is excellent, and it is delicate and slender. A simple cap 7 can be obtained. Further, the inner cap 7A and the outer cap 7B are engaged with each other only at the upper fitting portion at the upper end and the lower fitting portion at the lower end, and the upper and lower peripheral surfaces between both fitting portions are opposed to each other via the gap 35. According to the cap 7, the peripheral wall of the outer cap 7B can be flexibly deformed to absorb the impact when a drop impact, a bending force, or the like acts on the outer cap 7B. The impact force is reduced, and the protection function of the working head 3 covered with the inner cap 7A can be further enhanced.

The lower fitting portion is composed of a flange wall 25 bulging out on the outer surface of the opening of the inner cap 7A, and an inner wall 34 of the opening of the outer cap 7B fitted on the flange wall 25, and faces the flange wall 25. According to the cap 7 in which the reinforcing ribs 33 of the opening inner wall 34 are bulged on the outer peripheral surface of the outer cap 7B, the wall strength of the opening peripheral portion of the outer cap 7B that has been subjected to the external force is improved, and the opening peripheral wall is formed. Since the bending deformation or breakage can be prevented well, the structural strength of the cap 7 can be further improved, and the separation preventing effect of the engagement structure provided between the inner surface of the inner cap 7A and the mounting portion 17 is improved. However, it is possible to prevent the cap 7 from coming off the mounting portion 17.

The upper fitting portion is composed of a projection 32 provided on one of the inner cap 7A and the outer cap 7B and a projection hole 28 provided on the other.

Side faces the intersection of the front and rear circular arc surfaces 30 and 31 with petal cross section. it can. In the case of a cylindrical body with a petal cross section, both arc surfaces 30/3
Since the thickness of the intersection of 1 is thicker than that of the other, it is difficult to clearly see the intersection line of the inner surface by adjusting the amount of light. This is because it is difficult to see a slight displacement of the sheet end. In addition, since each of the sheet portions 41 and 42 is curved along the two arc surfaces 30 and 31, a force in a direction approaching the intersection portion tends to act on the sheet end portion. It can also correct the misalignment. In the loaded state, the decorative sheet 7B is not wrinkled, and the side edge of the sheet portion does not overlap back and forth, so that the appearance of the cap 7 is improved.

The protrusion 32 of the upper fitting portion is provided on the inner cap 7A, and the positioning portion 43 of the decorative sheet 22 is provided on the protrusion 32.
