An expansion tank, includes: a tank main body defining a storage chamber storing a coolant liquid therein; multiple partition walls provided in the tank main body to divide the storage chamber into multiple division chambers including an inlet chamber and an outlet chamber, the partition walls being formed with communication holes for bringing adjacent ones of the division chambers into communication with each other; a coolant liquid inlet portion that is provided on the tank main body and is open to the inlet chamber; a coolant liquid outlet portion that has an outlet opening in a depression formed in a bottom of the tank main body and is open to the outlet chamber; and a barrier wall extending from a side wall of the tank main body or one of the partition walls into the depression.

Expansion tank

An internal combustion engine, includes: a cylinder block; a crankshaft rotatably supported in the cylinder block; an oil pan fastened to a lower end portion of the cylinder block; a chain case fastened to one end wall of the cylinder block in an axial direction of the crankshaft; a belt wound around a crank pulley provided on an end portion of the crankshaft protruding from the chain case and an accessory pulley provided on an engine accessory; and a tensioner contacting a back surface of the belt and applying a tension to the belt, wherein the tensioner includes multiple fastening portions, such that one of the fastening portions is fastened to at least one of the cylinder block and the chain case, and another one of the fastening portions is fastened to the oil pan.

Internal combustion engine

Formed in a pinion () are pinion-side helical external teeth (A) that mesh with a ring gear), and pinion-side helical internal teeth () that mesh with a pinion inner (). Formed in the pinion inner () are pinion inner-side helical external teeth () that mesh with the pinion-side helical internal teeth (). The configuration is formed so that when the rotational speed of the pinion () is slower than that of the ring gear (), a thrust load is generated in a direction toward the ring gear (), and when the rotational speed of the pinion () is faster than that of the ring gear (), a thrust load is generated in a direction away from the ring gear ().

Starter

A starter includes an output shaft which rotates by a rotary force applied from the motor unit, a housing in which an end of the output shaft is rotatably supported, and an electromagnetic device configured to apply/shut off current to the motor unit, and biases a suppressing force toward the ring gear to the pinion gear through a clutch mechanism, wherein a load receiving member which abuts one end of the output shaft to receive an axial load generated from the output shaft is installed in the housing.
