To provide a descending window opening and closing auxiliary tool capable of designing a thickness to be compact and improving durability.SOLUTION: A descending window opening and closing auxiliary tool 1 includes: a body 2 arranged below a descending window; and an arm 4 capable of revolving vertically with a roller 4a on its tip. The body 2 includes a link unit 6, a spring unit 8, and a support unit 12 inside. The link unit 6 is composed in a both-lever mechanism with a part of the body 2 as a fixed joint. The arm 4 is attached to a prime mover joint 6a of the both-lever mechanism to be capable of revolving integrally. The spring unit 8 has coupling metal fittings 8b, 8c coupled to both ends of coil springs 8a arranged in parallel. The coupling metal fitting 8b on one end of the spring unit 8 is coupled to a coupling point 6cc on a follower joint 6c of the both-lever mechanism and a coupling joint 8c on the other end is supported by the support unit 12 through a spring fixing pin 10. A virtual straight line which is in parallel with a stretching direction of the spring unit 8 and passing through the coupling point 6 cc is configured to always pass through in between the joints on both ends of the follower joint 6c.SELECTED DRAWING: Figure 1
