  • Patent number: 10738796
    Abstract: A fan frame of an axial-flow fan is provided to reduce the vibration generated during the rotation of the impeller that is transmitted to the outside of the axial-flow fan via the fan frame. The fan frame includes a housing, a base and a plurality of connection members. The base includes a shaft-coupling portion. Each of the plurality of connection members includes two ends respectively connected to the housing and the base. Each of the plurality of connection members is defined with an extension line passing through the two ends of the connection member. Each of the plurality of connection members includes a first bending portion and a second bending portion. The first bending portion extends around a first notch, and the second bending portion extends around a second notch. The extension line extends through the first and second notches.
