• a chain tensioner configured to apply tension to the third chain;
• and
• a bracket including a first end portion and a second end portion that are disposed in a direction substantially orthogonal to an axial direction of the crankshaft, and a connecting portion that couples the first end portion and the second end portion, wherein
• the bracket is fastened at the first end portion and the second end portion to the cylinder block,
• the second end portion is parallel to the first end portion,
• the connecting portion is spaced apart from the cylinder block,
• the first chain guide is fastened to the first end portion and the second chain guide is fastened to the second end portion, and
