A compressor housing includes an intake port, a scroll, and a shroud. The shroud includes a shroud surface facing the impeller, a sliding member in an annular shape, and a sliding-member fixing portion in an annular shape. An inner circumferential surface of the sliding member defines the shroud surface. The sliding-member fixing portion includes contact portions that are configured to such that an inner circumferential surface of the sliding-member fixing portion and an outer circumferential surface of the sliding member at least partially come into contact with each other. The sliding member is fastened to the sliding-member fixing portion at the contact portions by the fastening members. The sliding member is fastened by the fastening members configured to extend through the sliding-member fixing portion. The fastening members are fastened from an outer circumferential surface of the sliding-member fixing portion to the sliding member.

A rocker arm unit constituting a valve gear includes a support member, a rocker arm including a roller and walls opposed to each other with the roller being interposed between them and a wire member bridging the support member side and the rocker arm side with each other. The walls have shaft holes into which both ends of a shaft member rotatably supporting the roller extend respectively. The walls have lengthwise ends connected to each other via a receiving portion supported on a top of the support member so that the rocker arm is swung. The wire member has an extending portion extending from the support member side to the rocker arm side and having a distal end. The rocker arm side includes a part located away from the receiving portion. The distal end of the extending portion serves as an engagement portion engaging the rocker arm side part.

A rocker arm installed moduleis constructed by installing the cam shaft, the rocker armand the pivotto the housing. The housingis provided with a drop-off preventing meansfor supporting and preventing the rocker arm, which is disposed on the pivot, from dropping off. The rocker arm installed moduleis constructed by disposing the rocker armamong the camof the cam shaft, the pivotand the drop-off preventing meansin the housingto form a module, the module being configured to be disposed in a concave portionof the cylinder headwhile preventing the rocker armfrom dropping off.

The present invention provides a variable valve mechanism which includes a rotating cam provided on a camshaft, a swing arm that contacts with the rotating cam to swing, a drive arm that drives a valve in conjunction with the swing arm, a variable arm that turns the drive arm around a swing axis of the swing arm, an actuator that drives the variable arm, and cam device that is provided between the swing arm and the drive arm. The variable arm is provided so as to be able to rotate relatively around the same axis as the swing arm, and the cam device changes the initial position of the drive arm with respect to the swing arm accompanying the turning of the drive arm.
