Title:
OPENING/CLOSING MEMBER DRIVING DEVICE AND TOILET LID OPENING/CLOSING UNIT
Document Type and Number:
Japanese Patent JP2023125400
Kind Code:
A
Abstract:
To provide an opening/closing member driving device that can prevent grease coated on a gear part of an output shaft from adhering to a detection part of a potentiometer that detects the rotation of the output shaft and to the substrate.SOLUTION: A case 10 of an opening/closing member driving device 3 includes a partition portion 55 that divides the case 10 by an output shaft 11 and a second direction X2 of a sixth composite gear 35. A substrate 14 to which a detection unit 38 of a potentiometer 15 is attached opposes the partition portion 55 in a first direction X1 of the partition portion 55. The detection unit 38 is located in a gap C between the partition portion 55 and the substrate 14. A through-hole for a potentiometer gear 39 is provided on the partition portion 55. The potentiometer gear 39 has a gear body portion 52 that meshes with a gear portion 24 for detecting a rotary angle position of the output shaft 11 in the second direction X2 of the partition portion 55. A mating portion 51 mates with a gear connecting portion 38a of the detection unit 38 in the first direction X1 of the partition portion 55. The partition portion 55 is interposed between the detection unit 38, the substrate 14, and the output shaft 11.SELECTED DRAWING: Figure 6
