PURPOSE:To easily make a read by arranging a wiper member made of a rod type magnet whose center part is formed in a recessed shape inside the window of a meter, and moving the wiper member from outside the meter and removing drops of water sticking inside the window of the window of the meter. CONSTITUTION:The nearly square-sectioned wire member 8 formed of a plastic magnet or elastic rubber magnet so that respective surface center parts are formed in the arcuate recessed shape is arranged below the internal surface of the window 2 of an external box part 1. When it is difficult to read a metered value because of drops of water or dew sticking on the internal surface 2A of the window 2, a wiper operating tool 9 formed similarly to the member 8 is brought into contact with the front surface 2B of the window 2 to attract the member 8 and the operating tool 9 is slid up-and-down to sweep away the drops of water or dew. Consequently, the metered value, etc., is easily read.
