- the operators 203 configured to operate the shutter (lid portion) 200, which covers the opening windows 210 in an openable and closable manner, are formed at the end portions 1c in the front face 1a of the electric razor 1.
- the operators 203 are provided at the positions deviated to the right or left from the position in the front face 1a of the electric razor 1 where the user's thumb is placed when the user grips the grip portion 2. Accordingly, the user of the electric razor 1 can be prevented from accidentally operating the operators 203, which are configured to open or close the opening windows 210, while using the electric razor 1.
- the opening windows 210 are formed at the end portions 1c in the front face 1a of the electric razor 1, and the operators 203 are provided in the regions (cover portions 202) of the shutter (lid portion) 200 that cover the opening windows 210. This facilitates transmission of the force applied to the operators 203 for opening or closing the opening windows 210 to the regions (cover portions 202) that cover the opening windows 210, thus improving the operability of the shutter (lid portion) 200.
- the switch portion 22, which moves the outer and inner blades 51 and 54 relative to each other, is provided on the front face 1a of the electric razor 1. The user can, therefore, operate the switch portion 22 and operators 203 with one hand, thus improving the usability of the electric razor 1.
- the electric razor 1 includes the plural opening windows 210. Accordingly, in the washing process, one of the opening windows 210 can be designed to function as a water inlet while another one can be designed to function as a water outlet, so that the space portion S can be cleaned more efficiently.
- the antiskid portion 24 is provided at the central portion 1b on the front face 1a of the electric razor 1.
- the antiskid portion 24 is provided in the central portion 1b of the front face face 1a of the electric razor 1 in such a manner, it is possible to prevent slippage of the user's thumb placed on the grip portion 2 when the user grips the grip portion 2. This can more reliably prevent the operators 203, which is configured to open or close the opening windows 210, from being accidentally operated.
- the antiskid portion 24 is provided below the operators 203. Accordingly, if the user' s thumb placed when the user grips the grip portion 2 moves to the right or left, the operators 203 are not located in the range to which the user's thumb moves. It is, therefore, possible to prevent the operators 203, which are configured to open or close the opening windows 210, from being accidentally operated.
- the edges 54d of the inner blades 54 are configured to vertically overlap the opening windows 210 in the front view of the electric razor 1.
- the opening windows 210 are thus formed near the edges 54d of the inner blades 54 where body hair tends to accumulate, so that the accumulating body hair can be discharged from the opening windows 210 more smoothly.
- edges 54d of the inner blades 54 are configured to vertically overlap the opening windows 210 in the front view of the electric razor 1 independently of the locations of the inner blades 54 reciprocating relative to the outer blades 51. This allows body hair to be discharged from the opening windows 210 still more smoothly.
- the inner blade attachment portions 131 and 141 are configured not to vertically overlap the opening windows 210 in the front view of the electric razor 1. Accordingly, water introduced from the opening windows 210 collide with the inner blade attachment portions 131 and 141 and cannot reach deep inside (the back side).
