  • connection portion 73 It engages with the periphery of the snap fit hole portion 223 of the side surface, that is, the connection portion 73 . As a result, the connection between the connected portion 63 and the connecting portion 73 is completed, and the assembly of the accelerator device 100 and the reaction force applying device 10 is completed.
  • the cross-sectional shape of the connected portion 63 is a non-perfect circular shape.
  • the cross-sectional shape of the connecting portion 73 is a non-perfect circular shape. Therefore, as in the second embodiment, the relative rotation between the pedal housing 110 and the actuator housing 20 can be suppressed, and variations in the relative positions of the two can be further reduced.
  • the connected portion 63 and the connecting portion 73 are connected by snap-fitting. Therefore, the connected portion 63 and the connecting portion 73 can be easily and reliably connected, and the connection between the connected portion 63 and the connecting portion 73 can be maintained even after the accelerator device 100 and the reaction force applying device 10 are assembled. , variations in the relative positions of the pedal housing 110 and the actuator housing 20 can be reduced over a long period of time.
  • the lever 40 contacts the arm 50 that rotates together with the pedal 120 to apply a reaction force to the pedal 120 .
  • the lever 40 may directly contact the pedal 120 to apply a reaction force to the pedal 120 without providing the pedal 120 with the arm 50 .
  • the second embodiment shows an example in which the connecting part and the connecting part are connected by press-fitting
  • the third embodiment shows an example in which the connecting part and the connecting part are connected by snap-fitting
  • the connected portion and the connecting portion may be connected by press-fitting and snap-fitting.
  • the cross-sectional shape of the connected portion and the connecting portion may be a non-perfect circular shape such as an elliptical shape, an elliptical shape, or a polygonal shape other than a rectangle.
  • the wall surface of the floor panel of the vehicle to which the reaction force applying device and the accelerator device are attached may not be parallel to the yz plane. That is, the wall surface of the floor panel may be formed at any angle with respect to the vehicle.
