PROBLEM TO BE SOLVED: To provide a vibration suppression member which can efficiently suppress vibration transmission from a power unit to a powered part. SOLUTION: The vibration suppression member 25 is a member used to couple the power unit and powered part and composed of a power unit coupling the part 25a, an elastic member 25c, and a powered part coupling member 25b, and has the elastic member 25c arranged between the power part coupling member 25a and powered part coupling member 25b to couple the both with each other. The elastic member 25c is provided with a hole part 25c-1. In this arrangement, the natural vibration frequency of the device is adjusted by adjusting a spring constant through adjustment of the volume of the hole part 25c-1 of the elastic member 25c of the vibration suppression member 25 so that no resonance to a vibrating component of an exciting source is generated. Thus vibration of a specific frequency area is suppressed by attenuating the resonance frequency component, and consequently the vibration transmission from the power unit to the powered part is effectively suppressed.
