Since a continuous fiber of a fiber-reinforced resin member (11) includes an axial fiber (19) aligned in the axial direction and an axially right-angled fiber (20) aligned at right angles to the axial direction, and the density of the axially right-angled fiber (20) of a first layer (17) on the outer side of the corner part (13) is made higher than the density of the axially right-angled fiber (20) of a second layer (18) on the inner side of the corner part (13), when an axial load is input and the fiber-reinforced resin member (11) breaks, the axially right-angled fiber (20) disposed at high density in the outside first layer (17) of the corner part (13) is actively stretched and breaks, thereby enabling a large energy-absorbing effect to be exhibited. Moreover, the fiber-reinforced resin member (11) has a simple structure in which merely the density of the axially right-angled fiber (20) in its interior is changed, thereby minimizing any increase in the production cost. |
