PURPOSE: Work board structure for a counterweight is provided to use a work board at work, and to move the work board to the inside of the ceiling of a car for reducing the noise and vibration of an elevator during the operation of the elevator. CONSTITUTION: A work board(10) is composed of a fixing frame(12) containing plural connect holes; a support piece forming a compartment unit by being crossly installed to the central portion of the fixing frame; and a foothold settled to the compartment part formed by the fixing frame and the support piece. The work board is installed to a mount base(64) formed on an upper portion of a car(50) with a bolt(20) and a nut(22). A worker gets on the foothold and does the counterweight work. The distance between the work board and the counterweight is adjusted by moving the work board through the connect holes. After finishing the work, the connect device is unfastened and the work board is turned in the opposite direction. Thus, the work board is not protruded from a ceiling plate(52) of the car by connecting the work board to the mount base with a connect device.
