摘要： Provided is a valve opening/closing timing control device in which oil channels are formed with a high degree of accuracy at low cost. The valve opening/closing timing control device includes: an advancing chamber and a retarding chamber that are formed by partitioning a fluid pressure chamber that is formed between a driving rotating body and a driven rotating body that is located on an inner circumference side of the driving rotating body so as to be relatively rotatable, with a partitioning portion that is provided on an outer circumference side of the driven rotating body; an advancing channel that is in communication with the advancing chamber; and a retarding channel that is in communication with the retarding chamber. The driven rotating body has: a first member that is cylindrical and is provided with the partitioning portion; and a second member that is cylindrical, has a rotational axis that is the same as a rotational axis of the first member, and has a portion that overlaps an inner side of the first member at least in a radial direction of the first member, out of the radial direction of the first member and an axial direction, and the advancing channel and the retarding channel are formed to penetrate through a boundary between the first member and the second member after the first member and the second member have been installed.

摘要： Provided is a valve opening/closing timing control device that makes it easier to reduce the weight of a driven rotating body while ensuring the strength thereof, and also makes it easier to downsize the entire device. The valve opening/closing timing control device includes: a driving rotating body; a driven rotating body; a fixed shaft portion by which the driven rotating body is supported coaxially with the driving rotating body; a fluid pressure chamber between the driving rotating body and the driven rotating body; a partitioning portion that partitions the fluid pressure chamber into an advancing chamber and a retarding chamber; and a phase control unit for controlling a rotation phase of the driven rotating body relative to the driving rotating body by supplying/discharging a pressurized fluid to/from the advancing chamber or the retarding chamber via an inside of the fixed shaft portion. The driven rotating body has: an inner circumferential member that has a cylindrical portion, and a coupling plate portion of the camshaft, the cylindrical portion and the coupling plate portion being integrated with each other; and an outer circumferential member provided with the partitioning portion. The outer circumferential member is provided with the inner circumferential member in a unified manner so as to have the same rotational axis. The inner circumferential member is formed with an iron-based material. The outer circumferential member is formed with a material that is lighter in weight than the iron-based material.

摘要： Provided is a valve opening/closing timing control device that makes it easier to timely control the rotation phase of a driven rotating body (3) relative to a driving rotating body (1). The valve opening/closing timing control device includes: the driving rotating body (1); the driven rotating body(3); an advancing chamber (5a) and a retarding chamber (5b) that are formed by partitioning a fluid pressure chamber between the driving rotating body (1) and the driven rotating body (3); and a phase control unit for supplying a pressurized fluid to the advancing chamber (5a) or the retarding chamber (5b) via an advancing channel (11 a) or a retarding channel (11 b) that are formed to penetrate through the driven rotating body (3). In the driven rotating body (3), an outer circumferential member (3a) and an inner circumferential member (3b) are formed integrally with and coaxially with each other. The advancing channel (11 a) and the retarding channel (11 b) are located to form a predetermined angle. Between every pair of an advancing channel (11 a) and a retarding channel (11 b), a groove portion (23) is formed in one of an inner circumferential surface of the outer circumferential member (3a) and an outer circumferential surface of the inner circumferential member (3b), and an elongated protruding portion (24) is formed on the other, at a position that corresponds to the groove portion (23).
