Title:
DOOR OPENING/CLOSING DEVICE
Document Type and Number:
Japanese Patent JP2022158215
Kind Code:
A
Abstract:
To provide a door opening/closing device that makes it possible to enhance the degree of freedom of selection and the degree of freedom of arrangement of a driving source.SOLUTION: A door opening/closing device of the embodiment includes: a reduction gear device 31 having an output shaft 30 that outputs a rotational force; a drive pulley 33 having a drive shaft 33a to move the door in an opening/closing manner by receiving the rotational force of the output shaft 30; a rod 62 connected to a latch that unlocks the door; and a transmission mechanism 100 capable of transmitting the output of the output shaft 30 to the rod 62 and the drive pulley 33. The transmission mechanism 100 has: a female screw 101 connected to the output shaft 30 rotatable about the output shaft 30 and movable in an axial direction along the output shaft 30; a male screw 102 connected to the drive shaft 33a rotatable about the drive shaft 33a; and a transmission member 103 for transmitting a forwarding force to the rod 62 when the female screw 101 moves while engaging the male screw 102 by receiving the rotational force output by the output shaft 30 in the fully closed position of the door.SELECTED DRAWING: Figure 6
