Provided is a balance with a windshield having a door to be smoothly opened and closed either manually or automatically. Provided is an electronic balance (1) with a windshield including a balance main body (30) including a weighing mechanism connected to a weighing pan (31), a windshield (10) having doors (11) capable of opening and closing by sliding, and configured to form a weighing chamber (6) by covering the weighing pan (31), and actuators (60) configured to open and close the doors (11), wherein the actuator (60) includes a double-acting type air cylinder (40) having two ports (44, 46) serving as air intake ports, an air pump (62) to be connected to the two ports (44, 46), two valves (66) respectively interposed between the air pump (62) and the two ports (44, 46) and configured to make the ports (44, 46) communicate with and shut off from the atmosphere, and a control device (34) configured to control the two valves (66) to make the two ports (44, 46) communicate with the atmosphere when the air pump (62) is stopped. Without a special mechanism, switching between automatic opening and closing and manual opening and closing can be made, and in either automatic or manual opening and closing, the doors (11) of the windshield (10) are smoothly opened and closed.
