PROBLEM TO BE SOLVED: To reduce torque variation of both of an input shaft and an output shaft of an intermittent indexing device by one mechanism to suppress an influence of vibration on the intermittent indexing device caused by the variation of torque.SOLUTION: An intermittent indexing device 1A for converting continuous rotating motion of an input shaft 3 into intermittent rotating motion of an output shaft 4, includes: a cam device having a cam 10 disposed on the input shaft 3, and a cam follower 11 fixed to the output shaft 4 and engaged with the cam 10; and a torque compensation device having a torque compensation cam 13 disposed on the input shaft 3, a torque compensation cam follower 14 engaged with the torque compensation cam 13, and a torque compensation rotary body 15 disposed so as to be connected to the torque compensation cam follower 14, and reducing torque variation acting on the input shaft 3. The torque compensation rotary body 15 is arranged so that a rotating shaft 16 is arranged so as to be coaxial with the output shaft 4, and a direction of rotation acting on the output shaft 4 and a direction of rotation of the torque compensation rotary body 15 are the same direction.SELECTED DRAWING: Figure 1 【課題】一つの機構で間欠割出装置の入力軸と出力軸との両方のトルク変動を軽減し、トルク変動に起因する間欠割出装置への振動の影響を抑制する。【解決手段】入力軸３の連続回転運動を出力軸４の間欠的な回転運動に変換する間欠割出装置１Ａであって、入力軸３に設けられたカム１０と、出力軸４に固定され、カム１０に係合するカムフォロア１１とを有するカム装置と、入力軸３に設けられたトルク補償カム１３と、トルク補償カム１３に係合するトルク補償カムフォロア１４と、トルク補償カムフォロア１４に連結するように設けられたトルク補償回転体１５とを有し、入力軸３に作用するトルク変動を軽減するトルク補償装置とを備え、トルク補償回転体１５は、回転軸１６が出力軸４と同一軸上になるように配置され、出力軸４に作用する回転の方向と、トルク補償回転体１５との回転の方向は同一方向である。【選択図】図１
