ABSTRACT:
A spring coupler comprises a casing, a drive member rotatably mounted within the casing including a main portion and a core portion fixedly connected thereto by staking manner, a driven member rotatably mounted within the casing including a main portion and a core portion fixedly connected thereto by stacking manner and engageable with the core portion of the drive member upon rotation thereof, and a coil spring disposed between the drive member and the casing so as to be engaged frictionally with the casing in the free state thereof and including a first tang and a second tang. In this spring coupler, the first tang and the second tang of the coil spring are engaged with the core portion of the drive member in rotation in one direction and the other direction respectively before the drive member is brought into engagement with the core of the driven member thereby reducing the radius of the coil spring whereas the first tang and the second tang of the coil spring are engaged with the core portion of the driven member in rotation in one direction and the other direction respectively, thereby expanding the radius of the coil spring. The main portion and the core portion are fixedly connected with each other by staking manner so that less time and less cumbersome operations are required for assembling the drive member and/or the driven member.
