Claims

[Scope of utility model registration request]

In response to the operation of the electromagnetic valve, the piston in the air cylinder reciprocates to cause the vertical screw shaft to reciprocate in the axial direction, and a rotatable and vertically movable hollow column that is threadedly engaged with the screw shaft is connected to the screw shaft. During upward movement, the door is first rotated by the torque induced from the component force on the screw slope to close the door, and after the closing operation of the door is completed, the screw shaft and the support are integrated, and the support is moved along with the door in a slightly vertical direction to the vehicle body. In the automobile door opening/closing drive device which locks the door relative to the vehicle body by raising the door relative to the vehicle body, the support supports the screws except for the closing operation completion position of the door during the rotation permissible angle given to the support support. A restraining member is attached to a part of the vehicle body through a screw, and the restraining member restrains the raising due to the component force induced from the engaging portion and defines the raising amount and the raising restriction position of the door at the closing operation completion position of the door. The locking member is attached so that the vertical position can be adjusted by rotation, and a locking member is removably provided on the outer periphery of the restraining member, which protrudes outward and restricts the rotation of the restraining member in the door opening direction by engaging with the fixed member. Automotive door opening/closing drive device.
