PROBLEM TO BE SOLVED: To provide a lubricating device for an internal combustion engine capable of improving lubrication efficiency by limiting supply of extra lubricating oil to a contact part between a cam and a driven object driven by the cam. SOLUTION: The lubricating device of the invention is the lubricating device for the internal combustion engine for supplying lubricating oil to the contact part C between the cam 6 and a rocker arm 5 of the internal combustion engine 1. The device comprises an oil pump 9 for sending the lubricating oil by pressure, a cam shower part 12 for supplying the lubricating oil to the contact part, a lubricating oil supplying passage 13 for connecting the oil pump 9 and the cam shower part 12, a shut-off valve 15 provided at the lubricating oil supplying passage 13 for switching the supply of the lubricating oil to the contact part C and stopping the supply, and a lubricating oil supply control means 18 for controlling operation of the shut-off valve 15 so as to start supplying the lubricating oil to the contact part C at the time of starting the internal combustion engine 1 and then to stop supplying the lubricating oil to the contact part C during the operation of the internal combustion engine 1.
