摘要： A planetary gear reduction system (1) has a sun gear (5), a plurality of planet gears (7), a ring gear (9), and a planet carrier (11). The planet carrier (11) has a first plate (17) supporting one ends of planet shafts (13) supporting the planet gears, a second plate (12) supporting the other ends of the planet shafts, and a cylindrical drum (19) connecting the first and second plates. The first plate has first portions supporting the one ends of the planet shafts; second portions connecting the first plate to the drum, the first and second portions being provided alternately in a circumferential direction; first cutouts each defined between the neighboring first and second portions, the first cutouts (53) each extending radially inwardly from a circumferential edge thereof to a position adjacent a circle passing centers of the planet shafts (13); and second cutouts (55) each defined radially inward of the second portion and between the neighboring two first portions, the second cutouts each extending radially inwardly from a first region outside the circle and a second region inside the circle (Pc).

摘要： This apparatus (1) includes: a sun gear (5) having external teeth; planetary gears (7), each having external teeth and configured to be meshed with the sun gear (5); planetary shafts (13), each being a rotation shaft of the planetary gear (7); a ring gear (9) having internal teeth and configured to be meshed with the planetary gears (7); and a planetary carrier (11) including an annular base plate (17) and an annular back plate (19). The planetary carrier (11) supports the planetary shafts (13) between the angular base plate (17) and the annular back plate (19) and determines a relative position between planetary gears (7). The annular base plate (17) is integrally formed with one end of the planetary shaft (13) to support the one end. The annular back plate (19) supports the other end of the planetary shaft (13). At least one of the planetary shaft (13) and the planetary carrier (11) has lower stiffness in its part adjacent to the one end of the planetary shaft (13) than stiffness of its part adjacent to the other end thereof.

摘要： A pivot cam mechanism included in a valve operating system (50a,50b) is configured such that a coupling pin (62) is supported at a pivot member (61) in a position closer to a camshaft (24,25) than a control shaft (60), and the pivot member (61) and the driven member (63) are integrally pivotable according to the rotation of the drive cam (24a) while changing relative attitudes of the driven member (63) and the pivot member (61). Positions and shapes of the drive cam (24a), the driven member (63), and the pivot member (61) are designed so that a valve maximum acceleration point at which an acceleration of a valve body (53) is maximum is located in a front part of a valve acceleration period in which the acceleration of the valve body (53) has a positive value while the drive cam (24a) is rotating once.
