つれて、しつかりしたものが要求される。 Generally, the switch handle of an electric razor is
As shown in FIG. 1, the switch handle 20 is disposed on one side of the front surface of the housing 1, and the switch handle 20 is small compared to the size of the housing 1, which poses a problem in operability. For this reason, it is desirable to use a large-sized switch handle that spans the entire front width of the housing.
If the housing is formed into a thin shape with a short front-to-back length, the strength of the housing will decrease, making it difficult in terms of strength to support a large switch handle such as the one mentioned above in a vertically movable manner. Additionally, as switch handles become larger, the click mechanism that reliably stops the switch handle in each of the upper and lower positions is required to be more sturdy.

る。 For this reason, considering the strength of the housing, as shown in Japanese Utility Model Application Publication No. 56-167439,
As a switch handle, 2/3 of the width of the housing
However, even with this width, it would be difficult to place the click mechanism between the front wall of the housing and the back of the switch handle. In terms of things,
A click mechanism is provided between the housing and the rear wall side of the housing via a member that penetrates the housing back and forth.

To provide an electric shaver that can reinforce the housing, ensure sufficient strength even when the housing is formed into a thin shape, and allow a large switch handle to be attached to the front surface of the thin housing without any trouble.

という利点がある。 As described above, in the present invention, the switch handle is attached over the entire width of the front surface of the housing, and the chassis on which the electrical components are mounted comes into contact with the rear surface of the front wall of the housing over almost the entire width, so that the front wall of the housing is attached to the chassis. The large switch handle that spans the entire width of the front of the housing can be operated for ease of use, and the front of the housing is reinforced with a chassis that allows the switch handle to be operated over the entire width of the front of the housing. It can reliably support the large switch handle that is attached to it, and even if the housing is made thinner by shortening the length from front to back, the housing will maintain sufficient strength and a large switch handle can be attached to this thin housing without any problems. It's something you can wear. In addition, since the click protrusion formed on the front wall of the housing is biased toward the click step on the back of the switch handle by a spring piece formed on a part of the chassis, there is a gap between the switch handle and the housing. The click engagement is strong, and even if the switch handle is made large, sufficient click action can be guaranteed.In addition, there is a power supply circuit opening/closing contact between the chassis where the electrical parts are mounted and the back of the switch handle. Since the contact member forming the part is provided, reliable operation can be expected for opening and closing of the power supply circuit, and there is an advantage that internal wiring is easy.

スイツチハンドルが停止される電気かみそり。 A housing with a built-in drive source that drives an inner cutter block whose front surface is approximately flat and protrudes from the top surface, and a drive source that is attached to the housing so that it can move vertically over the entire width of the front surface of the housing and that drives the inner cutter block that protrudes from the top surface. A switch handle for opening and closing the power supply circuit, and a chassis equipped with electrical components constituting the power supply circuit,
A chassis is disposed between the drive source and the rear surface of the front wall of the housing, contacts the rear surface of the front wall of the housing over substantially the entire width thereof, and lines the front wall of the housing.
A contact member is provided between the back of the switch handle and the contact for opening/closing the power circuit, and the back of the switch handle is formed with a click stepped part in which multiple valleys are arranged vertically through peaks, and the front of the housing is is provided with a click protrusion that is formed by cutting and raising a part of the front wall of the housing and that engages with any valley in the click step, and a spring piece formed on a part of the chassis is attached to the back surface of the click protrusion. An electric shaver in which the switch handle is stopped at a position where the click protrusions are pressed against each other so that the click steps are biased by an alligator spring, and the click protrusions are fitted into each valley.
