The invention provides a vehicle sunroof apparatus which can smoothly switch between an inkling motion state and a sling motion state without biting of left and right opening and closing diving units. The vehicle sunroof apparatus includes: a pair of left and right opening and closing drive units which can drive a moving panel to open and close according to the moving positions of the moving bodies moving in front and rear directions of a vehicle on rails. Each opening and closing drive unit possesses a switching mechanism which can switch the connecting states between the moving bodies and the moving panel through the moving of the moving bodies in a switching area. In addition, the electronic control unit (ECU) as a control device can detect load change generated when the moving bodies move forward in a switching area to switch the connecting states between the moving plate and the moving bodies, based on the rotation synonymous pulse signals Sp of a motor as a driving source. In addition, the ECU correspondingly allows each opening and closing driving units for reversely rotating the moving bodies to perform control when determining the switching of the connection states of the opening and closing driving units on left and right sides based on load change.
