The oil supply mechanism (14) includes a housing hole (101), a pump case (102), and a pump vane (103). The housing hole (101) is communicated with the oil supply hole (100). The pump case (102) is fitted in the housing hole (101). The pump vane (103) is housed in the pump case (102), and includes a large width portion (107) which is locked by the upper inner surface of the pump case (102).
