an axial direction of the annular body (21), wherein the key (22a) is configured to
be engaged with a corresponding sliding slot (16a) of a mating component (10) and
has a contact root (33, 34) and a circumferential end surface (31, 32) to be engaged
with the sliding slot (16a) whereby at least one of the keys (22a, 22b, 23a, 23b)
is provided with a hollow portion (26a, 26a', 26a", 26a"') located at the contact
root (33, 34), and an engagement wall (35, 36) with a predetermined stiffness and
being elastically deformable is formed between the hollow portion (26a, 26a', 26a",
26a"') and the circumferential end surface (31, 32).
