发明名称 VALVE GEAR OF INTERNAL COMBUSTION ENGINE
摘要 PROBLEM TO BE SOLVED: To reduce the size and weight of a sub-cam, and to improve follow-up performance of the sub-cam to a valve system cam, by devising arrangement of an energizing member to the sub-cam for constituting a transmission mechanism, in a variable vale gear of an internal combustion engine. SOLUTION: In this variable valve gear, the transmission mechanism T transmitting valve driving force of an intake cam 15a to an intake valve 11 and capable of changing a maximum lift quantity of the intake valve 11, has the sub-cam 40 having a roller 43 abutting on the intake cam 15a by being energized by the energizing member 60, a rocker arm 50 driven by the sub-cam 40, and a holder 30 rockably supporting the sub-cam 40 and the rocker arm 50 and driven by a control member 70. The holder 30 has a connecting wall 33 connecting a pair of arm parts 31a and 31b supporting the sub-cam 40. The energizing member 60 is arranged on both sides of the roller 43 in the direction of the locking center line Ls, and is held by the connecting wall 33. COPYRIGHT: (C)2008,JPO&INPIT
