Power tool having circuit board

A power tool comprising:

• a brushless motor;
• a housing formed with an outlet port and an intake port, the housing providing a cooling air passage extending therein from the intake port to the outlet port, the housing comprising:
• a motor housing accommodating therein the brushless motor and extending in a top-bottom direction;
• a hand-grip part which a user grips, the hand-grip part extending in the top-bottom direction, the hand-grip part being disposed rearward of and connected to the motor housing;
• and
• a connecting part connecting the motor housing to the hand-grip part;
• an output unit disposed above the brushless motor and extending in a front-rear direction;
• a power cable configured to be connected to a power source;
• and
• a circuit board unit connected to the power cable and extending in the front-rear direction, the circuit board unit being disposed below the brushless motor and in the connecting part, the circuit board unit comprising:
• a plurality of switching elements for driving the brushless motor;
• and
• a rectifying device configured to rectify an alternating current from the power source to a direct current,
• wherein the intake port is positioned below the brushless motor and opposite to the hand-grip part with respect to the connecting part in the front-rear direction, and the outlet port is positioned at an upper portion of the motor housing, and
• wherein the plurality of switching elements and the rectifying device are positioned on the cooling air passage and opposite to the hand-grip part with respect to the connecting part in the front-rear direction.
