To prevent a relative rotation of a spindle nut relative to a guide pipe effectively.SOLUTION: A vehicle door closing gear 1 according to the invention comprises a motor drive mechanism 30, a first housing 10 for accommodating the motor drive mechanism 30, a spindle drive mechanism 40 connected to the motor drive mechanism 30 and a second housing 20 arranged coaxially relative to the first housing 10 and for moving relatively to the first housing 10 by the spindle drive mechanism. The spindle drive mechanism 40 comprises a spindle 50 connected to the motor drive mechanism 30, a spindle nut 60 threaded into the spindle 50, a push rod 70 fixed so as not to execute a relative rotation relative to the spindle nut 60 and having a projecting part 71 at the periphery and a guide pipe 80 having a guide groove 81 for guiding the projecting part 71 of the push rod 70 in an axial direction.SELECTED DRAWING: Figure 2

    【課題】スピンドルナットのガイド管に対する相対回転を効果的に防止する。【解決手段】本発明の車両用ドア開閉装置1は、モータ駆動機構30と、モータ駆動機構30を収容する第1ハウジング10と、モータ駆動機構30に接続されたスピンドル駆動機構40と、第1ハウジング10に対して同軸状に配置され、スピンドル駆動機構によって第1ハウジング10に対して相対的に移動する第2ハウジング20とを備える。スピンドル駆動機構40は、モータ駆動機構30に接続されたスピンドル50と、スピンドル50と螺合するスピンドルナット60と、スピンドルナット60に対して相対回転しないように固定され、外周に突起部71が設けられたプッシュロッド70と、プッシュロッド70の突起部71を軸方向に案内するガイド溝81が形成されたガイド管80とを備える。【選択図】図2
