Abstract
A cylinder block includes a first bank, a second bank, and a press-fitting portion. The first bank and the second bank are arranged in positions offset from each other in a cylinder arrangement direction. The press-fitting portion is provided straddling a first end surface of the first bank and a second end surface of the second bank. The press-fitting portion has a hole. The first end surface protrudes in a direction in which the press-fitting portion protrudes in the cylinder arrangement direction, with respect to the second end surface. A thickness of the press-fitting portion in a radial direction of the hole at a first portion that is connected to the first end surface is thinner than a thickness of the press-fitting portion in the radial direction of the hole at a second portion that is connected to the second end surface.
