動モード可変式動弁装置。[Claim for Utility Model Registration] A Rocker arm that operatively engages an intake valve or an exhaust valve is attached to a Rocker arm shaft so as to be swingable and slidable in the axial direction, and a cam is attached to a camshaft that rotates synchronously with the engine crankshaft. Two valve train cams with different profiles are arranged adjacent to each other, and the rocker arm has a first position where it engages with one of the valve train cams and a second position where it engages with the other valve train cam. In a valve train with variable valve operating mode, the operating mode of the intake valve or exhaust valve is switched by sliding the Rodscar arm axially on the Rodscar arm shaft between means for elastically biasing the valve operating cam to the first position or the second position; and a locking mechanism that locks the rocker arm to the rocker arm shaft in a manner that allows the valve operating cam to be released at a predetermined timing; is pivoted to the rocker arm on the side facing the camshaft so as to be pivotable about an axis parallel to the rocker arm shaft, and has two pawls spaced apart from each other in the axial direction at intervals approximately equal to the width of the valve drive cam. a locking lever having an input portion at one end and an axially extending input portion at the other end; and a rocker arm configured to align with the pawl portion of the locking lever when the rocker arm is in the first and second positions. three notches provided axially apart from each other on the outer periphery of the shaft; spring means for biasing the latch lever such that the pawl portion engages the notch; and the pawl portion of the latch lever a plunger radially slidably mounted on a journal bearing of a camshaft opposite the input portion to push the input portion in a direction away from the notch; and a plunger engaged with an inner end of the plunger and arranged at the predetermined timing. and a timing cam provided on a camshaft to cause the plunger to protrude toward a locking lever input section.
