Then, the battery cover 6 is removed and the housing 1
The battery 30 having the positive and negative poles 8 arranged side by side from the lower opening 5 is inserted into the battery storage chamber 2, and the positive and negative contact springs 7 provided on the inner surface of the battery storage chamber 2 are connected to the battery. The positive and negative poles 8 are contacted. Outer blade 2 on outer blade frame 11
A cap 45 for protecting 0 is detachably locked, and the outer blade frame 11 is formed by two-color molding of synthetic resin so that the transparent portion 46 is partially formed on the outer blade frame 11. The reciprocating electric razor body is designed to show the inside without impairing the flow of the color scheme (design) from the reciprocating electric razor body.

[0010]

As described above, according to the present invention, positive and negative contact springs are provided in parallel on the inner surface of the battery storage chamber along the reciprocating direction of the inner blade. Is compressible in the direction perpendicular to the inner surface of the housing, the positive and negative poles are arranged side by side in the battery storage chamber, and the positive and negative contact springs contact the positive and negative poles of the battery. Therefore, the load of the contact spring is not applied to the battery lid, and as a result, the force is not received by the contact spring in the opening direction of the battery lid, and the reliability of fixing the battery lid is improved as compared with the conventional method. For example, even if the structure is exactly the same as the conventional fixing of the battery lid, the reliability of fixing is much improved as compared with the conventional case. In addition, the contact load of the contact spring can be set regardless of the structure of the battery lid, so the contact load does not vary due to the variation of the fixed position of the battery lid, and the contact reliability is further improved. It is also possible to set the load of the contact spring high in order to achieve this. Further, the battery is loaded by the contact spring in a direction perpendicular to the vibration direction of the inner blade and the reciprocating driver and perpendicular to the vertical direction of the housing, and the battery is vibrated by the vibration of the main body of the reciprocating electric razor. It is possible to suppress rattling and vibration, and since the spring load of the contact spring does not change as in the conventional case, the contact stability is improved as compared with the conventional case.
