To provide a downsized cam device capable of significantly reducing a pressure angle in a lift area of a cam to attain smooth operation, and provide machinery, a component, a bearing, a vehicle, and a machine manufacturing method.SOLUTION: A cam profile of a cam (20) has, at one end in a circumferential direction, a rotary end (28) where a cam shaft (22) cannot rotate in a reverse direction by a cam follower (30), and from the rotary end (28) to an opening end (29) being the other end in the circumferential direction, a cam surface (21) contacting with the cam follower (30) is provided. A distance between the other end in the circumferential direction of the cam surface (21) and the cam shaft (22) is made longer than a distance between the cam shaft (22) and the rotary end (28).SELECTED DRAWING: Figure 13 【課題】カムのリフト領域での圧力角を大幅に緩和して円滑な作動を図ると共に小型化されるカム装置、及び機械装置、並びに部品、軸受、車両、及び機械の製造方法を提供する。【解決手段】カム（２０）のカムプロファイルは、周方向一端において、カム軸（２２）がカムフォロア（３０）によって逆方向に回転不能となる回転端（２８）を有し、該回転端（２８）から周方向他端である開放端（２９）までカムフォロア（３０）が当接するカム面（２１）を備え、カム面（２１）の周方向他端は、カム軸（２２）からの距離が、カム軸（２２）と回転端（２８）との間の距離よりも大きい。【選択図】図１３
