PROBLEM TO BE SOLVED: To provide a torque cam device which can increase thrust which is generated according to torque to be transmitted, and can suppress a decrease of points at which a pressing member and a pressed member contact with each other.SOLUTION: A torque cam device comprises at least a first cam face 29 having a recess and a protrusion, and a second cam face 35 having a recess or a protrusion which is formed while being displaced from the recess or the protrusion in the first cam face 29 in a circumferential direction or a radial direction. The torque cam device also comprises a first cam follower 25 which abuts on the first cam face 29 when torque is transmitted to either of the pressing member or the pressed member, and transmits the torque, and a second cam follower 26 which abuts on the second cam face 35, and transmits the torque. 【課題】伝達されるトルクに応じて生じる推力を大きくすることができるとともに、押圧部材と被押圧部材とが接触する箇所が減少することを抑制することができるトルクカム装置を提供する。【解決手段】凹部および凸部を有する第１カム面２９と、第１カム面２９における凹部または凸部と円周方向および半径方向にずれて形成された凹部または凸部を備えた第２カム面３５とを少なくとも備え、押圧部材と被押圧部材とのいずれかにトルクが伝達されたときに、第１カム面２９に当接してトルクを伝達する第１カムフォロアー２５と第２カム面３５に当接してトルクを伝達する第２カムフォロアー２６とを備えている。【選択図】図１
