PROBLEM TO BE SOLVED: To improve the durable lifetime of a torque sensor while elastically performing the relative movement in a continuous gear train area by providing a device for elastically absorbing the relative movement between a structural member and a cam disc capable of being shifted in the axial direction so as to reduce the abrasion in areas of gear train and an opposite gear train. SOLUTION: A torque sensor arranged in front of a conical disc 1 capable of being moved along a driving shaft A of a conical pulley wrapping connector device is formed of a cam disc 8 provided at a constant position in the axial direction, a cam disc 12 capable of being shifted in the axial direction, and a spherical body 10 as an opening body provided between both the discs 8, 12. The cam disc 8 is integrally bonded to a driving gear 2 through a gear train 6, and a gear train 14 formed in the axial area 12b outside in the radial direction of the cam disc 12 is provided in structural members 17, 20 so as to cooperate with an opposite gear train 16. A plate spring 30 is arranged between the axial area 12b and the annular structural member 17, and with this structure, fine movement and pumping movement are absorbed.
