Abstract:
1. A pedal module comprising: a double coil spring that includes an outside coil and an inside coil, wherein the inside coil is placed inward of the outside coil in a radial direction of the outside coil; a pedal that turns in a forward direction when an external depressing force is applied thereto, wherein the pedal turns in a reverse direction, which is opposite from the forward direction, when a restoring force of the double coil spring is applied thereto; and a damping part that is made of an elastic material and has an inserting portion, which is disposed between the outside coil and the inside coil in the radial direction of the outside coil, wherein: the inserting portion includes a first side end portion, a slant surface portion, and a middle portion, which are arranged one after another in a direction of width; the middle portion protrudes axially away from the first side end portion in a direction of length of the inserting portion, toward an axial end of the outside coil, for preventing the occurrence of abnormal noises and the deterioration of feeling of depressing the pedal; the slant surface portion has a flat planar surface, which is generally flat in a state where the external depressing force is not applied to the pedal; the flat planar surface of the slant surface portion is configured to abut against and to be radially inwardly guided along one of a plurality of windings of the outside coil, and deflected radially inward by the one of the plurality of windings to a location radially inward of the outside coil, when the pedal is turned in the forward direction to compress the outside coil and the inside coil; and an angle θ
