Claim:
A method of manufacturing a carriage of a scroll wheel assembly configured to hold a rotatable scroll wheel, the method comprising: providing a scroll wheel with an axle and a circumferential surface; forming a single-piece carriage as a component distinct from a housing of a mouse in which the single-piece carriage may be mounted, the single-piece carriage integrally having: first and second sides defining a wheel well, first and second axle guides integral to the single-piece carriage, respectively formed as part of the first and second sides of the carriage, configured to hold an axle of the scroll wheel, and an integral follower arm on the first side of the carriage, the follower arm having a follower on an end of the follower arm and extending toward the wheel well from the first side of the carriage, the follower being configured such that when the scroll wheel is coupled to the single-piece carriage, the follower is in contact with the circumferential surface of the scroll wheel and biased to resist deflection as the scroll wheel rotates.
