PURPOSE: A metering device is provided to easily confirm metering data regardless of the situation of working sites by including a displaying part in a main part and displaying metered data on the displaying part. CONSTITUTION: A central shaft(15) is protruded from a main body(10), and an insertion hole(25) is formed in a metering part(20). The central shaft is inserted into the insertion hole. A stopper(16) is protruded from the central shaft, and a protrusion(26) is installed in the insertion hole in order to limit the rotation angle of the stopper. A spherical guiding hole(18) is supported by an elastic spring. A plurality of supporting grooves(27) with constant intervals is formed in the metering part.
