Abstract
An oil circulation device for an internal combustion engine includes an oil pan, a partition, and a communication groove. The oil pan is disposed below a cylinder block and includes a bottom wall and a sidewall to define a recessed portion that opens upward. The partition extends upward from the bottom wall so as to have a protruding end and divide the recessed portion into a first recessed portion and a second recessed portion. The communication groove extends downward from the protruding end of the partition in a thickness direction of the partition to connect the first recessed portion and the second recessed portion.
