To provide an exhaust valve driving device capable of stabilizing the opening/closing control of an exhaust valve by suppressing a variation in the mounting position of the exhaust valve driving device on a mounted object to suppress an increase in the position variation of an output shaft.SOLUTION: Each of exhaust valve driving devices 10, 10b-10i includes an output shaft 26 connected to an exhaust valve 19 arranged in an exhaust pipe 13 via a link mechanism 25, a housing 35 having a through-hole 76 which passes through in the direction parallel to a rotation axis direction AX3 of the output shaft and into which a fastening body 78 used for fixing the exhaust valve driving device to each of mounted objects 24, 24b-24i is inserted, and each of position fixing parts 70, 70b-70g, 70h1, 70i1 for determining the mounting position of the exhaust valve driving device on the mounted object.SELECTED DRAWING: Figure 6 【課題】取付け対象体に対する排気バルブ駆動装置の取り付け位置のばらつきを抑制して出力シャフトの位置ばらつきが大きくなることを抑制し、排気バルブの開閉制御を安定させることができる排気バルブ駆動装置を提供する。【解決手段】排気バルブ駆動装置１０，１０ｂ〜１０ｉは、排気管１３に配置されている排気バルブ１９とリンク機構２５を介して接続されている出力シャフト２６と、出力シャフトの回転軸方向ＡＸ３と平行な方向に貫通し、排気バルブ駆動装置を取付け対象体２４，２４ｂ〜２４ｉに固定するために用いられる締結体７８が挿入される貫通孔７６を有するハウジング３５と、取付け対象体に対する排気バルブ駆動装置の取り付け位置を決める位置固定部７０，７０ｂ〜７０ｇ，７０ｈ１，７０ｉ１と、を備える。【選択図】図６
