Claims

[Scope of utility model registration request]

An opening through which the crankshaft is inserted is formed at the rear end of the joint between the cylinder block and the oil pan fixed to the lower part of the cylinder block, and an opening is formed at the edge of the semicircular hole on the oil pan side that forms the opening. A flange portion having a downward U-shaped cross section, and an arc-shaped seal member fitted into the U-shaped portion of the flange portion, and a rear plate joined to the rear end surface of the cylinder block. In the seal structure in which the seal member is compressed to seal a gap in the opening where the crankshaft faces, the seal member is attached to the seal member main body toward the inside of the flange portion of the semicircular hole of the oil pan. An oil pan seal structure characterized in that a biasing member is attached to the oil pan.
