Claims

[Scope of utility model registration request]

In a manifold catalytic converter in which a monolithic catalyst having an oval cross section is housed in a cast iron catalyst case having an oval cross section directly below an exhaust manifold, the monolithic catalyst is a cylindrical body having an oval cross section, and the monolithic catalyst is cushioned inside. a holding cylinder that is held through a material and a sealing material, the outer circumferential surface of the longer diameter side is in contact with the inner surface of the longer diameter side of the catalyst case, and the holding cylinder has a gap between the outer circumferential surface of the shorter diameter side and the inner surface of the shorter diameter side of the catalyst case; What is claimed is: 1. A manifold catalytic converter comprising: a slit extending over the entire length of the holding cylinder in a direction along the axis of the holding cylinder;
