A coolant supply device (1) for supplying coolant to a friction plate unit (61), said coolant supply device being equipped with: an axial extension part (30), which is arranged so as to extend in the axial direction (L) coaxially with an inside support member (62) supporting inside friction plates (61B); and a circumferential extension part (20) connected to the axial extension part (30) and extending in the circumferential direction. A circumferential liquid passage (23) is formed in the interior of the circumferential extension part (20). Multiple through-holes (32) are formed at different positions in the circumferential direction in the axial extension part (30), and an axial liquid passage (33), which connects each of the through-holes (32) and the circumferential liquid passage (23), is formed in the axial extension part. |
