An annular step (73) is formed on an inner wall (51) of an intake member (50). The annular step (73) includes an upstream wall portion (74), a downstream wall portion (76), and a connecting wall portion (75). The connecting wall portion (75) connects a first connecting end (75a) of the upstream wall portion (74) and a second connecting end (75b) of the downstream wall portion (76) with each other. The second connecting end (75b) of the downstream wall portion (76) is disposed at a more outward position than the first connecting end (75a) of the upstream wall portion (74) in a radial direction (Dr) of the intake member (50), and the connecting wall portion (75) extends outwardly in the radial direction (Dr) of the intake member (50) from the first connecting end (75a) toward the second connecting end (75b).
