Title:
VARIABLE VALVE GEAR OF INTERNAL COMBUSTION ENGINE AND ASSEMBLY METHOD OF VARIABLE VALVE GEAR
Document Type and Number:
Japanese Patent JP2019052569
Kind Code:
A
Abstract:
To provide a variable valve gear of an internal combustion engine which can achieve improvement of axis alignment between an inner cam shaft and a rotor to improve assemblability.SOLUTION: A variable valve gear of an internal combustion engine includes: an inner cam shaft 6 which is inserted into an outer cam shaft 5 while enabling relative rotation; a first shaft part 5a extending from one end part of the outer cam shaft; a housing 2 which has a first insertion hole 20 into which the first shaft part is inserted and which is fixed to the outer cam shaft; and a second shaft part 6a which extends from one end part of the inner cam shaft and protrudes from the first shaft part in a rotation axis direction. A rotor part 17 which is disposed within the housing while enabling relative rotation and is fixed to the second shaft part has a second insertion hole 21 into which the second shaft part is inserted before the first shaft part is inserted into the first insertion hole.SELECTED DRAWING: Figure 1
