The shavers described in these publications have a disadvantage that the side cutter lever is liable to twist when sliding. The reason is that a part of the side cutter lever is slidably connected to the main body case with a switch knob. The twist of the side cutter lever causes the rod end of the side cutter lever to come off the side cutter. If the rod comes off from the side cutter, the side cutter cannot be raised or lowered even if the switch knob of the side cutter is moved up and down. Therefore, the shaver of this structure has a drawback that the side cutter cannot be stably raised and lowered with the switch knob.

[0005] The present invention has been developed with the aim of solving these disadvantages.
