Beschreibung
Zusammenfassung:	An exhaust gas cleaning catalyst for a saddle-type vehicle, the catalyst including a support; a first catalyst layer formed on a surface of the support; and a second catalyst layer formed on the first catalyst layer, wherein the first catalyst layer includes a carrier formed of a composite oxide having a CeO 2 content of 45 to 70 mass%, a ZrO 2 content of 20 to 45 mass%, an Nd 2 O 3 content of 2 to 20 mass%, and an La 2 O 3 content of 1 to 10 mass%, and a catalyst component which is supported on the carrier and contains metallic Pd or Pd oxide; and the second catalyst layer includes a carrier formed of a composite oxide having a zrO 2 content of 50 to 95 mass%, a CeO 2 content of 0 to 40 mass%, an Nd 2 O 3 content of 2 to 20 mass%, and an La 2 O 3 content of 1 to 10 mass%, and a catalyst component which is supported on the carrier and contains metallic Rh or Rh oxide, or both metallic Rh or Rh oxide and metallic Pt or Pt oxide.
