摘要： A planet bearing has a single row of spherical rolling elements between an outer wheel and an inner wheel. A planet gear is supported by the outer wheel from a radially inner side. A planet carrier supports the inner wheel from a radially inner side. An elastic component is interposed between the inner wheel and the planet carrier. A driving rotor or a driven rotor has a thrust bearing part that supports the planet gear from one side in the axial direction. The outer wheel is in contact with the spherical rolling element at a rolling contact point and defines a contact angle on the one side in the axial direction.

摘要： A planetary rotor includes: a planetary gear engaged with a driving rotor and a driven rotor on an eccentric side; and a single sequence type planetary bearing having an outer ring held by the planetary gear, an inner ring supported by a planetary carrier in the radial direction and receiving a restoring force from an elastic component, and a plurality of spherical rolling elements interposed between the outer ring and the inner ring. The outer ring is arranged to form a rolling contact part in contact with the spherical rolling element on the eccentric side, with a contact angle to a specific side in the axial direction. A thrust-bearing part where the driving rotor is supported by the driven rotor on the specific side and on the eccentric side is located closer to a rotation center line of the driven rotor than the rolling contact part is.

摘要： A valve timing controller includes a lock mechanism that locks a rotation phase at a main lock phase when an internal combustion engine is started with an ambient temperature more than or equal to a preset temperature. The main lock phase represents a rotation phase set for closing an intake valve at a later timing later than a timing when a piston reaches a bottom dead center of a cylinder in the internal combustion engine. The lock mechanism locks the rotation phase at a sub lock phase representing a rotation phase advanced rather than the main lock phase in the internal combustion engine when the internal combustion engine is started with an ambient temperature lower than the present temperature.

摘要： A valve timing controller includes a driving rotor, a driven rotor, a planetary rotor, a planetary carrier, and an elastic component to produce a restoring force biasing the planetary rotor to an eccentric side such that the driving rotor is inclined to the driven rotor. The driving rotor has an inclination angle θ1 relative to the driven rotor in a first inclination state where the driving rotor is in contact with the driven rotor on both sides in the axial direction. The inclination angle θ1 is smaller than an inclination angle θ2 in a second inclination state where the driving rotor is in contact with the driven rotor on both sides in the radial direction, and is smaller than an inclination angle θ3 in a third inclination state where the driving rotor is in contact with the camshaft on both sides in the radial direction.

摘要： A valve timing controller has a driving rotor, a driven rotor, and a planet gear engaged with the driving rotor and the driven rotor to control a rotation phase of the driven rotor relative to the driving rotor by carrying out planet movement. The driven rotor has a contact surface in contact with a tip end of a chamfering portion of a camshaft, and a feed port passing through the driven rotor in an axial direction to introduce lubricant supplied from the camshaft into the driving rotor. The feed port has an outer edge part located on a radially outer side. The outer edge part, on a side adjacent to the contact surface, is located on a radially outer side of the tip end of the chamfering portion and is located on a radially inner side of an outer circumference part of the journal portion.

摘要： In a definition cross-section of a planet gear located on an eccentric side in a radial direction relative to a driving rotor and a driven rotor, an imaginary straight line is defined by connecting a center of a planet side outer arc part that configures a raceway groove of a planet outer wheel on the eccentric side to a center of a solar side outer arc part that configures a raceway groove of a solar outer wheel on an opposite side opposite from the eccentric side. A planet side inner arc part of a planet inner wheel and a solar side inner arc part of a solar inner wheel are located on the imaginary straight line in the definition cross-section.

摘要： A main lock member is fitted in a main lock bore at a main lock phase for closing an intake valve at a timing later than a timing when a piston reaches a bottom dead center, whereby a rotation phase is locked. In a subordinate lock mechanism, the rotation phase is locked at a subordinate lock phase advancing further than the main lock phase. In a lock control mechanism, a temperature sensing body is changed to an expanded state, whereby a moving member is latched at a first position in which the main lock member is allowed to be fitted in the main lock bore, whereas at a main lock phase in a cold stop state after a timing when the temperature of the stopped internal combustion engine becomes less than a preset temperature, the temperature sensing body is changed to a contracted state.

摘要： A sealing structure has a permanent magnet and a magnetic-flux guiding member for guiding magnetic flux of the permanent magnet to a brake shaft of a brake rotating member. The magnetic-flux guiding member surrounds an outer periphery of the brake shaft so as to form a sealing gap around the brake shaft. The sealing gap is communicated to a fluid chamber, in which magnetic viscous fluid is filled. A fluid sealing member is provided at the brake shaft at a housing outer side of the magnetic-flux guiding member to form an intermediate fluid chamber, in which an intermediate fluid made of non-magnetic liquid is filled.
