PROBLEM TO BE SOLVED: To provide an armrest structure capable of preventing an armrest or the like from obstructing getting on and off and resting the entire arm without obstructing the operation of a controller. SOLUTION: The rear column part 26 of an armrest support 23 is freely turnably supported so as to move a front column part 25 in a horizontal direction between a using position nearer to a seat 11 and a retracting position away from the seat 11. A lock pin 30 whose lower end is tapered projection shape is provided on the lower end part of the front column part 25 so as to be vertically protruded and retreated, and a lock hole 14b long in the front and rear direction and engaged with the lock pin 30 at the using position is opened upwards and provided on the front part upper surface of the frame side part 14 of a seat frame 13. The armrest 21S on the side of the controller 3 is formed relatively short so as to arranged a front end part behind the wrist when a user places the arm and the armrest 21L on the opposite side is formed relatively long so as to arranged the front end part in front of the wrist when the user places the arm.
