PROBLEM TO BE SOLVED: To solve a conventional problem that a tamper-evident ring at a lower end of a skirt of a cap body has a large separation space below the tamper-evident ring for easy recognition of separation, so that the cap body cannot be supported from downward when the cap is mounted and the cap cannot be prevented from failing to engage. SOLUTION: In the tamper-evident cap device, a positioning protrusion 12 with which the skirt 2 of the cap body 1 comes into contact to position a cap mounting completed position when the cap body 1 is mounted on a container neck 4 is provided on the container neck 4. In addition, a bridge 3 is provided between the cap body 1 and the tamper-evident ring 10 to be located outside the positioning protrusion 12.
