Abstract: A bearing device includes: a journal part, a main bearing, a cylinder block, and a bearing cap. One half bearing held by the cylinder block includes: a first circumferential oil groove and a second circumferential oil groove being formed at positions opposite to an inlet of an oil passage of the journal part; a separation part separating the first circumferential oil groove and the second circumferential oil groove; and an oil hole penetrating from the first circumferential oil groove to an outer circumferential surface. A length L1 in a circumferential direction of the separation part at a position in the inner circumferential surface of the one half bearing is smaller than a length L2 in the circumferential direction of the inlet of the journal part.

Abstract: A main bearing includes first and second half bearings, each having a main cylinder portion and crush relief portions in both circumferential end portions. An oil groove circumferentially extends on an inner circumferential surface only of the first half bearing, one circumferential end portion of the oil groove opens on a circumferential end surface on a front side in a rotation direction, and the other circumferential end portion of the oil groove is positioned in the crush relief portion on a rear side in the rotation direction. The first half bearing includes a transition region between the crush relief portion on the front side in the rotation direction and the main cylinder portion, and the second half bearing includes a transition region between the crush relief portion on the rear side in the rotation direction and the main cylinder portion.
