A displacement diagnosis sensor of a brake pedal having a stop lamp switch function is provided. According to the present invention, one sensor performs both a function of a stop lamp switch and a function of diagnosing a rotational displacement of the brake pedal simultaneously to thereby save a manufacturing cost and reduce a weight.

An electronic organ type accelerator pedal apparatus, may include a pedal housing having a pedal arm receiving space therein and a carrier fitting hole, a pedal pivotally hinged to a hinged portion of the pedal housing, a pedal arm pivotally mounted to an inner surface of the pedal housing, wherein one end portion of the pedal arm is elastically biased by an elastic member and the other end portion of which is pivotally coupled to the pedal through the carrier fitting hole to transfer an activating force of the pedal to the other end portion of the pedal arm, and a damping stopper fixed to the inner surface of the pedal housing in the pedal arm receiving space and selectively engaged with the other end portion of the pedal arm to limit a rotation of the pedal arm when the pedal arm is rotated by the elastic member.

A hybrid method manufacturing apparatus for a torsion beam according to an exemplary embodiment of the present invention includes a pair of side punch molds where a semi-finished product material heated to approximately 880 to 800&#xb0; C. is molded and a press mold where a cooling water circulation line decreasing the temperature of the processed finished product to approximately 750 to 450&#xb0; C. while the semi-finished product material is molded to a processed finished product is installed, an advantage of high-temperature molding having high dimensional accuracy is maintained at the time of manufacturing the torsion beam and additional heat treatment such as tempering is selectively performed only when additional heat treatment such as tempering increases toughness because only a martensite structure is not formed in quenching treatment.
