PROBLEM TO BE SOLVED: To enable an angle posture of a rotary blade based on an axis of an operation pipe to be changed more lightly and easily without causing increase of the weight and enlargement of a tip part of the operation pipe. SOLUTION: The portable power bush cutter 1 has the operation pipe 10, a transmission shaft 40 passed through the operation pipe 10, and the rotary blade 31 supported by a rotary blade-supporting member 30 installed in the tip part of the operation pipe 10, and is constituted so that the rotary output of a power source may be transmitted through the transmission shaft 40 to the rotary blade 31 to rotate the rotary blade 31. The rotary blade-supporting member 30 is supported by the operation pipe 10 so as to be turnable around a horizontal shaft 14 orthogonal to the axis of the operation pipe 10 in the plan view with a prescribed resistance. The transmission shaft 40 has flexibility at least at the part from the tip part of the operation pipe 10 to the rotary blade-supporting member 30, and the part having the flexibility is passed through a bellows pipe 100 connected with the tip part of the operation pipe 10 at one terminal, and connected with the rotary blade-supporting member 30 at the other terminal.
