Zusammenfassung: | PURPOSE: To provide a work machine capable of holding a driven shaft in a protective pipe so as to compensate crossing and buffer vibration and surely preventing the heating of a supporting sleeve part. CONSTITUTION: The driven shaft (3) is held inside the supporting sleeve part (7) with a large supporting clearance (LS), a holding rib (9) is constituted so as to provide elasticity in a radial direction and a fastening rib (8) extended almost in the radial direction is arranged so as to be distributed to the peripheral direction of the supporting sleeve part (7) on the side of the holding rib (9). The fastening rib (8) is positioned with an interval (s) in the radial direction to the inner surface (21) of the protective pipe (1). |
