摘要: A return spring (35) is formed using a compression coil spring that is installed so that its axial direction is an updown direction. The return spring (35) is provided in a high-pressure chamber (14), and powers a plunger (20) in an upwards direction. A coil diameter of the return spring (35) varies along the axial direction. When the return spring (35) is in a maximally compressed state, an axial direction dimension (updown direction dimension) is smaller than a dimension that is a thickness of a spring wire (36) multiplied by the number of coil turns. Hence, an overall height of a lash adjuster A can be reduced in comparison to when a return spring with a constant coil diameter over an entire length is used.

摘要: A variable valve mechanism includes a first cam and a second cam, a main arm that drives a valve when swinging, a first sub arm that swings when pressed by the first cam, a second sub arm that swings when pressed by the second cam, and a switch device. The switch device includes a first switch pin that moves between a first coupled position between the main arm and the first sub arm and a first uncoupled position, and a second switch pin that moves between a second coupled position between the main arm and the second sub arm and a second uncoupled position. Both switch pins are arranged so as to be displaced from each other in positions where these switch pins do not overlap at least during a base circle phase in which base circles of both cams act.

摘要: A bearing device includes a support (12) having a bearing hole (15), a shaft member (11) slidably inserted into the bearing hole thereby to be rotatably supported by the support, the shaft member having an axial end surface and a locking part (16) located on the axial end surface of the shaft member to protrude in an axial direction of the shaft member from an outer periphery of the axial end surface of the shaft member. The locking part is deformed by force applied to its axial protruding end so as to bulge outward in a radial direction intersecting the axial direction, so that the bulging part is capable of being locked to a peripheral part of the bearing hole on an outer surface of the support.

摘要: The present invention provides a variable valve mechanism of an internal combustion engine, which includes a rocker arm that is driven by a cam so as to swing to drive a valve, a switching pin that is attached to the rocker arm so as to be shifted between a first position and a second position, a shift device that shifts the switching pin from the first position to the second position, and a return spring that returns the switching pin. In the variable valve mechanism, a drive state of the valve is switched by shifting the switching pin, the rocker arm is formed to have such a dimension that one end of the switching pin is exposed while projecting outward from the rocker arm, and the return spring is externally fitted to the one end of the switching pin so as to be exposed outside the rocker arm.
