摘要： Disclosed is a variable compression ration mechanism (5) in which a control shaft (10) is rotated and driven by an electric motor (21) through a wave gear reducer (22). The wave gear reducer (22) includes: a first internal gear member (31); an external gear member (32) arranged concentrically inside the internal gear member (31); a wave generator (33) having an oval outer shape and arranged inside the external gear member (32); and a second internal gear member (34), wherein a ratio of the number of teeth of a fixed gear portion (35) of the first internal gear member (31) to the number of teeth of a first gear portion (37) of the external gear member (32) is set greater than a ratio of the number of teeth of an output-side gear portion (42) of the second internal gear member (34) to the number of teeth of a second gear portion (38) of the external gear member (32).

Thus, the tooth depth of the output-side gear portion (42) of the second internal gear member (34) is made relatively large so as to attain a higher ratcheting torque and prevent ratcheting.

摘要： The control shaft (20) of a variable compression ratio mechanism is coordinated with the auxiliary shaft (25) of an actuator device (1) through an intermediate link (31). The housing (5) of the actuator device (1) has on the lower surface thereof an oil filter mounting seat section (36), and a stopper section (37) is formed integrally with the oil filter mounting seat section (36). A second arm (28) of the auxiliary shaft (25) comes in contact with the stopper section (37) to define the limit of the compression ratio on the low compression ratio side. The stopper section (37) has high rigidity because the oil filter mounting seat section (36) having high rigidity and the stopper section (37) are integrated together.
