摘要

A tire holding member for a tire testing machine (1) is provided with: a bottom rim (2), which is attached to the upper end of a bottom spindle (27) that is able to rotate around a central axis (A) in the vertical direction; a top rim (3), which is disposed above the bottom spindle (27) and which is attached to the bottom end of a top spindle (47) that is able to rotate around the central axis (A) with the bottom spindle (27); and a convex-sided member (4), which is separate to the bottom rim (2) and the top rim (3). One of the bottom rim (2) or the top rim (3) has a hole with the central axis (A) at the center thereof. The other of the bottom rim (2) or the top rim (3) has an end surface facing the one rim. The convex-sided member (4) is attached to the end surface of the other rim, and has a protruding section positioned closer to the hole side than the end surface side. The bottom rim (2) and the top rim (3) are positioned by each other in a state in which the center of each coincides at the central axis (A) due to the protruding section and the hole engaging with each other.
