Pedal effort generation device for vehicle

A pedal effort generation device for a vehicle, comprising:

• a pedal arm rotatably mounted on a pedal member in a front and rear direction;
• a connection link having one end at a rear side of the connection link hinged to the pedal arm;
• a rotating cylinder connected with the other end of the connection link and rotatably mounted on the pedal member;
• a follower unit mounted on the rotating cylinder, slidably coupled to the other end of the connection link, and configured to convert linear motion of the connection link into rotational motion of the rotating cylinder according to a front rotation of the pedal arm;
• an elastic mechanism connected with the pedal member and the rotating cylinder, elastically deformed upon a forward rotation of the rotating cylinder according to the front rotation of the pedal arm, and configured to provide a reverse restoring force to the rotating cylinder and the pedal arm with an accumulated elastic force;
• a rotation angle detecting sensor mounted on the pedal member, configured to detect a rotation angle of the rotating cylinder, and configured to output a detection signal to a controller;
• a support bush fixedly mounted on the pedal member and rotatably supporting the rotating cylinder, wherein
• the rotating cylinder is provided with at least one coupling protrusion coupled to the support bush,
• the rotation angle detecting sensor is disposed on the support bush, and
• the at least one coupling protrusion is provided as a magnetic body.
