An armrest is provided for use in vehicle operator enclosures that have limited space. It is mounted to the sidewall rather than to the seat and is pivotable between lowered and raised positions to provide greater clearance for entry into and exit from the enclosure. The armrest is ergonomically configured to support the operator's arm and hand and minimize fatigue as he manipulates the hand controls. It is L-shaped with a first fore and aft extending leg portion that has a generally U-shaped surface configured to receive the elbow, forearm and wrist of the operator. It further includes a second generally transversely extending leg portion that also has a fore and aft extending generally U-shaped surface that is aligned with the U-shaped surface of the first leg portion. The two U-shaped surfaces are aligned with the control to support the operator's elbow, forearm and wrist as he manipulates the control. For controls that are manipulated in a fore and aft direction such as levers, the U-shaped surface serves to allow sliding movement of the operator forearm while supporting it. For controls that require hand and/or wrist movements with little or no fore and aft arm movement, the second leg portion serves to support the wrist and hand.
