A shock absorbing member includes an outer peripheral wall having a polygonal cross-sectional shape and including a plurality of side portions, and a plurality of ribs, on an inner side of the outer peripheral wall, radially extending from a central axis and connected to an intermediate position of each of the side portions. A boundary position of adjacent side portions on an outer peripheral surface of the outer peripheral wall is defined as a vertex, an intermediate position of each side portion on the outer peripheral surface of the outer peripheral wall is defined as a rib connection point, and portions segmenting each of the side portion into two, with the rib connection point as a boundary, are each defined as a half-side portion.
