Abstract: An encoder applied to a rotatable device including a code disc set, at least one bearing, a bearing housing, a main housing, a sensor and an elastic assembly. The code disc set is disposed on a rotation end of the rotatable device. The bearing is disposed around the rotation end, and the bearing housing is disposed around the bearing. The main housing is connected with a first end of the bearing housing. The sensor is disposed on the main housing and corresponds to the disc wheel set, and there is an interval between the sensor and the code disc set. The elastic assembly is connected with a second end of the bearing housing and a fixing end of the rotatable device. Therefore, the interval between the sensor and the code disc set is maintained to be fixed, and the good position detection performance and stable signals are obtained.
