This device for measuring the weight of a vehicle is provided with an annular diaphragm (11) for covering the opening region (9d) of a groove part (9c) of an attachment part (7), and forming an oil chamber (9) of a prescribed space together with the groove part. The diaphragm (11) is hermetically secured by an inner collar (33) and an outer collar (35). The diaphragm (11) is pressed by a piston (43) that can be moved by the resilience of a spring in a suspension device. It is possible to change the pressure applied by the movement of the piston to a measurement fluid (R) filled in the oil chamber. The device is provided with a pressure sensor (21) that can detect changes in the pressure of the measurement fluid (R) filled in the oil chamber, the pressure sensor (21) communicating with the oil chamber.
