Japanese Patent JP6770381
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide an opening/closing device capable of performing an opening operation of an opening/closing body quickly and smoothly.SOLUTION: An opening/closing device 10 is configured so that, an opening/closing body 12 can be opened from a closed position to an open position. A drive output part 47 is driven to rotate by a drive motor. A drive input part 48 is driven to rotate by being fitted to the drive output part 47 with a play 52a, and opens and closes the opening/closing body 12. The drive output part 47 has a preceding contact part 47f which contacts the drive input part 48 when precedingly rotating in a normal rotation direction, and a delaying contact part which contacts the drive input part 48 when delayingly rotating. When the opening/closing body 12 is opened, the drive output part 47 rotates to an operation switching angle on a front side of an open position in a state in which the preceding contact part 47f contacts the drive input part 48, and the drive output part 47 rotated to the operation switching angle is regulated in rotation until the delaying contact part contacts the drive input part 48, and the drive output part 47 which contacts the drive input part rotates until the opening/closing body 12 reaches the open position.SELECTED DRAWING: Figure 5
