PROBLEM TO BE SOLVED: To provide a device certainly detecting the supply of lubricating oil. SOLUTION: In this device, a tip opening of a discharge pipe 8 for discharging each fixed volume of intermittently pressurized lubricating oil is disposed at a position communicating to a blast pipe 17 for sending air to a lubricated part, and the discharge of the lubricating oil is detected by a device for carrying and supplying the discharged lubricant oil to the lubricated part with airflow in the blast pipe. The opening of the discharge pipe 8 is blocked by a movable element 22 abutted on the tip opening with energizing force, and the movable element is moved against the energizing force by the discharging pressure of the lubricating oil to enable the opening to open. The discharge pipe and the movable element have conductivity, and a detecting means 40 is arranged, which applies a specified voltage between both of the discharge pipe and the movable element and detects an electrical change between both.
