Portable working machine e.g. brush cutter has elastic element whose surface, contact surface of holding portion and contact surface of housing, comprise concave or convex shape in longitudinal direction of control and/or adjusting rod

摘要

The machine has elastic elements which are placed between holder and the housing on each side of the longitudinal direction of control and/or adjusting rod (2). The end surfaces of each of the elastic elements in longitudinal direction of the control and/or adjusting rod to a contact surface of holder and contact surface of the housing have correct point. The surface selected from end surfaces of the elastic element, the contact surface of holder and the contact surface of housing, comprise a concave shape or convex shape in the longitudinal direction of control and/or adjusting rod.
