<P>PROBLEM TO BE SOLVED: To stably support a hood oscillatable and elevatable to an upward open attitude and a downward close attitude to the upward open attitude, and to simplify a removing operation of the hood. Ž<P>SOLUTION: This working machine pivotally supports the hood 11 to be oscillatable and elevatable to the upward open attitude and the downward close attitude by a pivotally supporting pin 23. A pivotally supporting pin hole 21 is provided with an opening 25 engaged or disengaged with the pivotally supporting pin 23 in a state of the hood 11 lowered from the upward open attitude. The working machine is provided with a hood supporting means 30 provided with a supporting pin 31 provided in the hood, a supporting pin hole 32 provided in a hood supporting body 22 and an opening 33 provided to engage/disengage the supporting pin 31 with/from the supporting pin hole 32. The supporting pin 31 is engaged into the supporting pin hole 32 as the hood is raised to the upward open attitude, and the hood supporting means is switched to an action state to support the hood at the upward open attitude. The supporting pin 31 is separated from the supporting pin hole 32 as the hood is lowered from the upward open attitude, and the hood supporting means is switched to an action releasing state.
