A chain guide attached to an engine block by a mounting bolt and slidably guiding a running chain, the chain guide comprising:

• a mounting part provided with a shaft hole through which the mounting bolt is passed;
• an oil jet passage for injecting lubricating oil, supplied to the shaft hole at a predetermined pressure, toward the chain;
• and
• in an attachment surface that is to be attached to the engine block, an oil inlet passage for making an oil supply port of the engine block and the shaft hole communicate with each other, wherein
• the chain guide is configured to be pivotable around the mounting bolt serving as a pivot shaft, and
• the oil inlet passage includes an oil collecting groove at a position opposite the oil supply port of the engine block, the oil collecting groove being formed to extend along a circular arc, with the pivot shaft being a center thereof.
