An electric compressor to be mounted on an engine in an engine compartment of a vehicle includes a compression mechanism, an electric motor, a motor driving circuit, a housing, a first mounting leg and a second mounting leg. The housing accommodates therein the compression mechanism, the electric motor and the motor driving circuit. The first mounting leg projects from the housing at a position adjacent to the compression mechanism. The second mounting leg projects from the housing at a position adjacent to the motor driving circuit. Each of the first mounting leg and the second mounting leg includes a fastening portion to be fastened to a portion of the engine and a connecting portion that connects the fastening portion with the housing. The connecting portion of the first mounting leg is made to be broken more easily than connecting portion of the second mounting leg.

A building assembly utilized in connecting building members together while permitting limited relative movement between the members. The assembly includes a structure such as a track or plate that includes one or more longitudinal slots. Integrally formed in the longitudinal slot is a breakaway washer that receives a fastener that extends into an adjacent structure. When a certain force is applied to the breakaway washer, the breakaway washer breaks away from the slot and this permits the slot to move about the breakaway washer and fastener which results in there being relative movement between two connected structures.
