Abstract
An electric motor is mounted on a body. The electric motor is driven by an electric driving unit. The electric driving unit is supported to the body by a vibration-proofing member. A natural frequency of a spring-mass system including the vibration-proofing member and the electric driving unit is higher than a frequency of a main component in vibration generated in the body during an operation.
