PROBLEM TO BE SOLVED: To provide a vehicle part structure for inhibiting vibration of a bracket for a vehicle door mirror or the like which is inexpensive, lightweight, and compact and, at the same time, can inhibit vibration such as moving of the image plane of a mirror while a vehicle is traveling, and an engine cover which damps noise to a great extent. SOLUTION: The vehicle part structure for inhibiting vibration is formed of a high rigidity synthetic resin composition having a logarithmic decrement of >=0.07 and a vibration absorption coefficient tanδof >=0.01, and a flexural modulus of 16,500 MPa, and damps vibration in early stage while suppressing resonance low by converting part of vibrational energy transmitted from the body side into heat energy.
