摘要

An electric driver (10) has a driver main body (20), a battery pack (30), a waterproof cover (40), a cover holder (29), and a waterproof cover support mechanism. The battery pack (30) is connected to a battery attachment part (28) of the driver main body (20). The waterproof cover (40) covers the battery pack (30) and the battery attachment part (28) with a bottomed cylindrical shape. The cover holder (29) is formed on the driver main body (20) so as to be in watertight contact with the entire peripheral edge of an opening (45) in the waterproof cover (40). The waterproof cover support mechanism supports the peripheral edge of the opening (45) of the waterproof cover (40) in a state of contact with the cover holder (29).
