Chainsaw

A chainsaw comprising:

• a housing;
• at least one handle coupled to the housing, the at least one handle including a handgrip to be gripped by a worker using the chainsaw;
• a guide bar coupled to the housing in such a manner as to protrude forwardly from the housing, the guide bar formed in an elongate plate shape having an outer periphery;
• a saw chain slidably provided around the outer periphery of the guide bar in such a manner as to be endlessly moved along the outer periphery;
• an electric motor provided inside the housing and operable to endlessly move the saw chain;
• an electric power supply;
• a main power switch provided electrically between the electric power supply and the electric motor, the main power switch being switchable between an ON state for enabling electric power feeding from the electric power supply to the electric motor, and an OFF state for disabling the electric power feeding;
• a trigger for controlling the electric power feeding from the electric power supply to the electric motor in a state in which the main power switch is switched to the ON state, to thereby control rotation of the electric motor;
• at least one detector provided in the handgrip and operable to detect whether or not the handgrip is gripped by the worker;
• and
• an interlocking device associated with the electric motor, the main power switch, the trigger and the detector, the interlocking device being configured to, when the trigger is manipulated to stop the rotation of the electric motor in a state in which the detector detects that the handgrip is gripped by the worker, maintain the ON state of the main power switch, and to, when the trigger is manipulated to stop the rotation of the electric motor in a state in which the detector detects that the handgrip is not gripped by the worker, switch the ON state of the main power switch to the OFF state.
