Claim 13:
14. A working machine comprising:
a motor;
a housing; comprising:
a main body accommodating the motor therein;
an operating element movable between an ON position and an OFF position relative to the main body, the motor being driven when the operating element is in the ON position, the motor being stopped when the operating element is in the OFF position; and
a shielding part configured to move relative to the main body as the operating element moves; and

an on-locking element provided in the housing, the on-locking element being supported by the main body so as to be movable between an on-lock position and an on-lock release position relative to the main body, the on-locking element maintaining the operating element in the ON position when the on-locking element is in the on-lock position, the on-locking element releasing an on-lock to the operating element when the on-locking element is in the on-lock release position;
wherein the operating element is configured to be in the OFF position while not being operated by an operator and to be in the ON position when operated by the operator, and
wherein, when the operating element is in the OFF position, the shielding part covers the on-locking element, making the on-locking element inoperable, and in a process of the operating element moving from the OFF position to the ON position, the shielding part moves relative to the main body and the on-locking element to expose the on-locking element from the shielding part, making the on-locking element operable.
