摘要： It has variable compression ratio mechanism (10) that changes engine compression ratio depending on the rotational position of first control shaft (14). First control shaft (14) and second control shaft, which is connected to a motor, are coupled together by lever (24) of coupling mechanism (20). First arm portion (25) of first control shaft (14) and one end of lever (24) are rotatably coupled together by first coupling pin (26). When viewed in the axial direction of this first coupling pin (26), at least at a given compression ratio position, first coupling pin (26) is arranged at a position away from bearing cap (30) that is for rotatably supporting first control shaft (14).

摘要： A lower link (6) is provided with an oil hole (30) in a crank pin bearing portion (11) in order to supply a jet of oil to a connecting portion between an upper pin (4) and an upper link (3). Oil hole (30) is composed of a first oil hole (31) linearly extending from the inner peripheral surface of crank pin bearing portion (11) outwardly in the radial direction, and a second oil hole (32) linearly extending from the outer surface of lower link (6) so as to intersect a distal end portion of first oil hole (31). An inclination angle (θ) of first oil hole (31) with a divided surface (14) set as a reference becomes relatively small, and hence the position of an oil inlet (31 b) involving a problem of stress concentration becomes closer to divided surface (14) exhibiting a relatively low stress. Consequently, the stress concentration at oil inlet (31b) is alleviated.

摘要： When a stopper portion is brought into abutment against body high-compression-ratio side stopper portion (35), when viewed in the control shaft axial direction, it is configured that the distance between body high-compression-ratio side stopper surface (42) and control-shaft high-compression-ratio side stopper surface (40) becomes relatively longer as being closer to the control shaft rotation center. Similarly, when a stopper portion is brought into abutment against body low-compression-ratio side stopper portion, when viewed in the control shaft axial direction, the distance between body low-compression-ratio side stopper surface and control-shaft, low-compression-ratio side stopper surface becomes relatively longer as being closer to the control shaft rotation center.

摘要： There are provided a variable compression-ratio mechanism (20) capable of varying an engine compression ratio in accordance with a rotational position of a control shaft (24); a speed reducer (44) configured to reduce in speed a rotational power of an actuator and transmit the speed-reduced rotational power to the control shaft (24); and a speed-reducer accommodating case (43) accommodating the speed reducer (44). An input shaft of the speed reducer (44) which is connected to the actuator has a shaft center line extending along a horizontal direction, and at least a part of the input shaft is kept under a lubricating oil retained in the speed-reducer accommodating case (43). The input shaft of the speed reducer (44) is swung by a predetermined swing angle to avoid inadequate lubrication of the input shaft of the speed reducer (44), during an operating state where the engine compression ratio is maintained constant.
