Rotation detection device and a vehicle pedal comprising such a device

A vehicle pedal, comprising a pedal shaft, a pedal part being rotatable around an axis of rotation which extends through a center of the pedal shaft and a rotation detection device for detection of rotation of the vehicle pedal around the axis of rotation, the rotation detection device comprising:

• a movable first part, which accompanies the rotational motion of the pedal,
• a stationary second part, wherein the first and the second part are arranged radially outside of the axis of rotation of the pedal and radially outside the pedal shaft,
• a magnetic field sensing component arranged in the first or in the second part and a magnetic element arranged in that part of the first or the second part that does not comprise the magnetic field sensing component, wherein the magnetic field sensing component generates an electric signal originating from magnetic interaction between the first and the second part when the first and the second part are moving in relation to each other, wherein the first part is coupled to the second part so that the motion of the first part is controlled in relation to the second part, and so that the magnetic element cannot move in a radial direction in relation to the magnetic field sensing component, wherein the first and the second part are coupled in such a way that the first part comprises a base part and at least one arm protruding from the base part and are arranged such that said at least one arm at least partly surrounds the second part, wherein at least one protrusion is arranged at said at least one arm of the first part, which is intended to cooperate with a first guide groove, arranged in the second part.
