The present invention relates to an anti-backlash gear device, used for an opening degree meter receiving a rotational force generated by a motor to enable a worm gear to transmit rotation to a unit to continuously designate a section of 270 degrees using an IND gear. A shaft hole or a corresponding shaft hole is configured to be elongated or both the shaft hole and the corresponding shaft hole are configured to be elongated. The anti-backlash gear device comprises an elastic unit pressing a gear unit having a gear shaft provided to the housing to be capable of controlling a central discharge of the gear shaft through the elongated hole to change a pressing angle starting from a basic circle and fixates a contact ratio through the elastic unit to prevent backlash from occurring in the gear. |
