ABSTRACT:
A scroll wheel device for computer mouse is disclosed, which comprises: a scroll wheel, having a scraggly structure formed in the interior thereof; and an adjusting unit. In an exemplary embodiment, the scraggly structure can be a sawtooth-like structure patterned on a circumferential area of a hollowed portion formed inside the scroll wheel; and an adjusting unit is further comprised of an adjusting rod and a braking part, in which the braking part, being made of an elastic material, can be an elastic strip; and the adjusting rod is formed with screw thread. Thereby, by rotating the adjusting rod, the braking part is driven to move along the adjusting rod in response to the rotation of screw thread so that the relative position of the braking part with respect to the scraggly structure is changed accordingly and thus the braking mode of the scroll wheel device is changed. Therefore, simply by rotating the adjusting rod, the braking mode of the scroll wheel device can be adjusted for customizing the scroll wheel device to cope with varying preferences of different users.
