PROBLEM TO BE SOLVED: To provide a valve lift adjusting device which can suppress the breakage of an operation member and the erroneous operation of a slider.SOLUTION: A slider 20 is formed with: a first protrusion 32 which protrudes to a radial outside direction rather than a radial external face 21 of the slider 20 at a position opposite to a rotation direction with respect to a first inclined face 26 of a first engagement groove 22, and can push back an operation pin 41 push backed to the radial outside direction by the first inclined face 26 to further radial outside direction; and a second protrusion 34 which protrudes to the radial outside direction rather than the radial external face 21 of the slider 20 at a position opposite to a rotation direction with respect to a second inclined face 31 of a second engagement groove 27, and can push back the operation pin 41 which is pushed back by the first inclined face 26 to the radial outside direction to a further radial outside direction. Accordingly, since the operation pin 41 does not contact with the first engagement groove 22 and the second engagement groove 27 even if the operation pin slightly protrudes to a radial inside direction by an influence of wobbling at attachment, the breakage of the operation pin 41 and the erroneous operation of the slider 20 can be suppressed. |
