An encoder includes a driven wheel, a housing, a carrier, a magnetic spur gear and a magnet. The driven wheel includes a first shaft bushing and a second shaft bushing. The housing includes a first shaft hole. The carrier includes a second shaft hole. The driven wheel is clamped between the housing and the carrier. The first shaft bushing is disposed within the first shaft hole. The second shaft bushing is disposed within the second shaft hole. The magnetic spur gear is installed on the driven wheel and synchronously rotated with the driven wheel. The magnet is located outside the magnetic spur gear and not contacted with the magnetic spur gear. When the driven wheel is rotated, a change of a magnetic attraction force between the magnetic spur gear and the magnet provides intermittent rotational resistance to the magnetic spur gear.
