している。The structure of the housing 2 of the electric drill 1 according to this embodiment is a housing 2 having the appearance of the electric drill 1. The housing 2 is provided by mounting a housing cover 5 for protecting the motor 4 on the main body housing 3. In the structure of the housing 2 of the electric drill 1 to be formed, when the housing cover 5 is mounted on the main body housing 3, the motor 4
A notch 7 for forming a gap 6 in the vicinity is provided at a joint 8 between the main body housing 3 and the housing cover 5.
