A vehicle sensor device comprising:

• a steering disk which is disposed on one side of a spindle and rotates according to a retraction operation or a pulling-out operation of a seat belt webbing;
• a bearing plate in which the steering disk is accommodated;
• a sensor housing which is installed to be rotatable based on an installation angle of the bearing plate and a change in an inclination of an object to be mounted;
• a ball which moves in the sensor housing according to a change in the inclination and acceleration of a vehicle;
• an upper cover which is disposed on an upper portion of the ball and rotatably disposed according to movement of the ball;
• a pilot lever which rotates in contact with the upper cover by rotation of the upper cover to be coupled to or decoupled from the steering disk;
• and
• a lock canceller lever which releases the contact with the steering disk and the pilot lever to rotate the steering disk, enabling the seat belt webbing to be retracted and pulled out.
