A valve opening and closing timing control device comprising: a driving-side rotating body that includes a sprocket around which a rotating body interlocked with a driving shaft of an internal combustion engine is wound and rotates in synchronization with the driving shaft; a driven-side rotating body that is supported by an inside of the driving-side rotating body to be rotatable coaxially with the same rotational axis and integrally rotates with a valve opening and closing cam shaft of the internal combustion engine; a bolt that is inserted into the driven-side rotating body to fix the driven-side rotating body to the cam shaft; a fluid pressure chamber that is formed by being partitioned between the driving-side rotating body and the driven-side rotating body; and a control valve that switches supplying and discharging of a hydraulic fluid with respect to the fluid pressure chamber such that a relative rotational phase of the driven-side rotating body with respect to the driving-side rotating body is changed between the most advance angle phase and the most retarded angle phase, wherein the bolt includes a male screw section in which the bolt engages with the cam shaft, and an abutting section at which exclusively a first portion which is formed on the outer periphery of the bolt and a holt hole which is formed on the inner periphery of the cam shaft abut each other in a direction orthogonal to an axial direction of the bolt in a region between the sprocket and the male screw section in the direction of the rotational axis, wherein a first circumferential groove that allows the hydraulic fluid to flow into the fluid pressure chamber or to flow out from the fluid pressure chamber is formed in an outer periphery portion of the bolt, and wherein the abutting section is configured of the first portion that is disposed on a rear side of the first circumferential groove in an inserting direction in the driven-side rotating body in the bolt, and the driven-side rotating body, or the cam shaft. a driving-side rotating body that includes a sprocket around which a rotating body interlocked with a driving shaft of an internal combustion engine is wound and rotates in synchronization with the driving shaft; a driven-side rotating body that is supported by an inside of the driving-side rotating body to be rotatable coaxially with the same rotational axis and integrally rotates with a valve opening and closing cam shaft of the internal combustion engine; a bolt that is inserted into the driven-side rotating body to fix the driven-side rotating body to the cam shaft; a fluid pressure chamber that is formed by being partitioned between the driving-side rotating body and the driven-side rotating body; and a control valve that switches supplying and discharging of a hydraulic fluid with respect to the fluid pressure chamber such that a relative rotational phase of the driven-side rotating body with respect to the driving-side rotating body is changed between the most advance angle phase and the most retarded angle phase, wherein the bolt includes a male screw section in which the bolt engages with the cam shaft, and an abutting section at which exclusively a first portion which is formed on the outer periphery of the bolt and a holt hole which is formed on the inner periphery of the cam shaft abut each other in a direction orthogonal to an axial direction of the bolt in a region between the sprocket and the male screw section in the direction of the rotational axis, a male screw section in which the bolt engages with the cam shaft, and an abutting section at which exclusively a first portion which is formed on the outer periphery of the bolt and a holt hole which is formed on the inner periphery of the cam shaft abut each other in a direction orthogonal to an axial direction of the bolt in a region between the sprocket and the male screw section in the direction of the rotational axis, wherein a first circumferential groove that allows the hydraulic fluid to flow into the fluid pressure chamber or to flow out from the fluid pressure chamber is formed in an outer periphery portion of the bolt, and wherein the abutting section is configured of the first portion that is disposed on a rear side of the first circumferential groove in an inserting direction in the driven-side rotating body in the bolt, and the driven-side rotating body, or the cam shaft.
