Abstract
Provided is a frame which is made of a fiber reinforced composite and where a bending strength and a vibration damping capability are compatible. The frame which is made of a fiber reinforced composite includes: a compressive wall part where a compressive stress occurs in a longitudinal direction of the frame when the frame receives a bending load in a normal direction perpendicularly intersecting the longitudinal direction; a side wall part extending in the normal direction and defining one of the corners with the compressive wall part; and a tension wall part which is away from the compressive wall part and extends in the longitudinal direction, and where a tensile stress occurs in the longitudinal direction when the frame receives the bending load. The tension wall part has a loss coefficient which is larger than a loss coefficient of the compressive wall part by 0.005 or more.
