To provide an exhaust gas purification system which is capable of purifying exhaust gas without a noble metal being carried, and maintaining exhaust gas purification performance even at high temperatures; a catalyst; and an exhaust gas purification method. A foamed metal catalyst (3) which is made of a transition metal element excepting platinum group elements and is formed of a metal having a porosity of not less than 80%, and which reduces NOx by being brought into contact with an exhaust gas having a hydrogen concentration of not less than a predetermined concentration (2%) and a temperature of not less than 230C, is provided in an exhaust gas passage (2) of an internal combustion engine (1) that discharges the exhaust gas.

Technology is provided that contributes to an improvement in the ease of assembly of transmissions. A fork mechanism (20) is configured in which fork rods (FS1, FS2, and FS3) to which shift forks (F1, F2, and F3) are connected are each attached to a pedestal (22) so as to be moveable in an axial direction. An assembly guide portion (30) is provided on the pedestal (22) and a guide pin (19) is erected on a clutch housing (12). As a result, even in cases where an input shaft (2) and a main shaft (4), on which driving and driven gears and synchro devices are assembled, are assembled on the clutch housing (12) in a state that the driving and driven gears are engaged and, thereafter the fork mechanism (20) is assembled on this clutch housing (12), the assembly of the fork mechanism (20) on the clutch housing (12) can be easily performed.

A vehicle shift operation apparatus has a shift lever (2) that is pivotally operated by a driver. A bracket (3) pivotally mounts the shift lever (2). An operation wire Wa connects the shift lever (2) and a vehicle transmission (K). Outer tubes (Wb1, Wb2) cover an external surface portion of the operation wire (Wa). A securing portion (4) secures the outer tube (Wb2) at a predetermined position. The transmission (K) is actuated through the operation wire (Wa) by pivotally operating the shift lever (2). A direction changing mechanism (5) is disposed between the shift lever connecting portion (2a) connected, with the operation wire (Wa), and the securing portion (4) of the outer tube (Wb2). The direction changing mechanism (5) may arbitrarily change the extending direction of the operation wire (Wa).
