Claims (11)

1. An electric tool having a housing comprising:

a cylindrical output part;

a grip part provided below the output part and extending in a direction intersecting with the output part;

a motor accommodated in the output part;

a cooling fan accommodated in the output part and coaxially-arranged with the motor;

a trigger switch accommodated in the grip part and provided to operate the motor, the trigger switch including a box shaped switch main body and a trigger part; and

an elastic member provided to fit a gap between an outer wall surface of the box shaped switch main body and a housing inner wall surface of the grip part by changing a shape of the elastic member according to a shape of the housing inner wall surface so as to form a partition wall in the housing between the output part and the grip part, the elastic member forming a circulation route of the cooling fan in the output part so as to isolate the circulation route from the grip part,

wherein the elastic member is adhesively fixed to an outer periphery of the box shaped switch main body such that the elastic member continuously winds the outer periphery of the box shaped switch main body from a first side to a second side via a rear side, and

wherein the elastic member is wound with an electric wire being closely contacted to the rear side of the outer periphery of the box-shaped switch main body, so that the electric wire is bed to the box-shaped switch main body.
