摘要: A first nitriding process step is performed in which a steel member is subjected to a nitriding process in a nitriding gas atmosphere having a nitriding potential with which a nitride compound layer having a γ′ phase or an e phase is generated, and thereafter a second nitriding process step is performed in which the steel member is subjected to a nitriding process in a nitriding gas atmosphere having a nitriding potential lower than the nitriding potential in the first nitriding process step, to thereby precipitate the γ′ phase in the nitride compound layer. It is possible to generate the nitride compound layer having a desired phase mode uniformly all over a component to be treated and to manufacture a nitrided steel member high in pitting resistance and bending fatigue strength.

摘要: An exhaust system for a saddle-ride type vehicle that can make it hard for the heat of a catalyst body to be transmitted to an external plate of a muffler. A catalyst body is installed in a muffler. An exhaust system has a tubular case covering the outer circumferential surface of the catalyst body along from the exhaust gas inlet to outlet of the catalyst body. The catalyst body is secured at its inlet-side end portion to one end portion of the case and the catalyst body is supported at its outlet-side end portion by the other end portion of the case. The case is supported at its outer circumferential surface by the front end portion of the muffler.

摘要: A saddle-ride type vehicle is capable of reducing influence of travelling wind on an open end of an air hose, thus preventing fluctuations in the internal pressure of a float chamber of a carburetor. The saddle-ride type vehicle includes a carburetor placed rearward of an engine and an air cleaner placed rearward of the carburetor. An air hose configured to regulate the internal pressure of a float chamber of the carburetor is connected to the carburetor. A recessed portion is provided at a side wall of an air-cleaner case of the air cleaner, the side wall being located along a lateral side of the vehicle. An open end of the air hose is placed at the recessed portion of the air-cleaner case.
