Abstract: A split-type sliding bearing for a crankshaft in an internal combustion engine incorporated in a split-type bearing housing. The sliding bearing consists of a pair of semi-cylindrical bearing bodies combined with each other to form a cylindrical body. The bearing housing has a cylindrical bearing retaining bore and consists of a pair of housing halves. One of the housing halves has a relatively lower stiffness, and the other has a relatively higher stiffness. One of the bearing bodies is held by the housing half having a relatively lower stiffness. The other bearing body is held by the housing half having a relatively higher stiffness. The bearing bodies have an equal outer diameter to each other, and both of the circumferential end parts of one bearing body have a larger thickness than those of the other bearing body prior to incorporation into the housing halves.
