  "textContent": "A shock absorbing member according to the present invention includes an outer peripheral wall (1) having a polygonal cross-sectional shape and including a plurality of side portions (2), and a plurality of ribs (5), on an inner side of the outer peripheral wall (1), radially extending from a central axis and connected to an intermediate position of each of the side portions (2). A boundary position of adjacent side portions (2) on an outer peripheral surface of the outer peripheral wall (1) is defined as a vertex (P3), an intermediate position of each side portion (2) on the outer peripheral surface of the outer peripheral wall (1) is defined as a rib connection point (P2), and portions segmenting each of the side portion into two, with the rib connection point (P2) as a boundary, are each defined as a half-side portion (2a and 2b), and when being compressively deformed in the axial direction, the two adjacent half-side portions (2a and 2b) sandwiching the vertex (P3) buckling-deform repeatedly in the axial direction while being deformed convexly and concavely in different directions in a radial direction, with positions of the outer peripheral wall (1) corresponding to the rib connection point (P2) and the vertex (P3) respectively as a node and an intermediate portion of each half-side portion (2a, 2b) as an anti-node.",
