Abstract
A pipe-shaped fixture () to be attached to a housing () of a work machine includes a fixture body () having a front-end projection () and a rear-end projection () that make front and rear limits of a rubber cushion () that encloses the fixture body () closely and circumferentially. The front- and rear-end projections () are connected to each other by a plurality of longitudinally extending ridges () formed at circumferential intervals. The ridges (), front- and rear-end projections () define a plurality of concavities () surrounded thereby on the outer circumference of the fixture body (). The front- and rear-end projections () cause longitudinal vibration of an operation rod () relative to the housing () to act as a compression force on the rubber cushion (), and thereby suppress longitudinal vibration of the operation rod () while maintaining effects of suppressing horizontal and vertical vibrations.
