A fan includes a frame, a rotor rotatably mounted in the frame, and a vane. The rotor includes a slot defined in the circumference of the rotor. The slot extends through an end surface of the rotor. The vane forms an installing portion to be inserted into the slot through the end surface. A first base and a second base are formed on the end surface at opposite sides of the slot. A blocking member is pivotably mounted to the first base with a first end, and is detachably engaged with the second base with a second end, to fix the installing portion in the slot.
