PROBLEM TO BE SOLVED: To provide a lubricating oil supply device capable of preventing the increase in drag torque by controlling the amount of lubricating oil supplied to a clutch to an appropriate amount with a simple structure.SOLUTION: Lubricating oil is supplied to the ports 211 and 213 of a pressure regulating valve from an oil pump driven by an internal combustion engine. The spool 202 of the pressure regulating valve has a first small diameter part 202a smaller in diameter than the inner diameter of a casing, and a choke part 205 is formed between the first small diameter part 202a and the casing. Lubricating oil flowing in through the port 211 is discharged from a port 214 via the choke part 205. The spool 202 is configured to move more in a right direction against the elastic force of a valve spring 203 as oil pressure in a pressure chamber 204 is higher and the length LCH of the choke part 205 through which the lubricating oil passes increases. |
