前記した左右方向検量装置においては、ローラ３の周面上に取り付けられた取付部材２９を荷重印加部３０によりローラ３の左右方向に引っ張ることにより、ローラ３に左右方向の荷重を印加しており、このときの荷重を荷重センサ３１により測定し、荷重センサ３１の荷重値と荷重測定部１４の荷重値とを比較することにより、荷重測定部１４の検量を行っており、荷重測定部１４を取り外すことなく、その左右方向の検量を容易に行うことができる。   In the left-right calibration device described above, a load in the left-right direction is applied to the roller 3 by pulling the mounting member 29 mounted on the circumferential surface of the roller 3 in the left-right direction of the roller 3 by the load application unit 30. The load at this time is measured by the load sensor 31, and the load measurement unit 14 is calibrated by comparing the load value of the load sensor 31 with the load value of the load measurement unit 14. It is possible to easily perform the calibration in the left-right direction without removing it.
