PROBLEM TO BE SOLVED: To provide a synthetic resin cap capable of closing an end part of a synthetic resin pipe at work for replacing a synthetic resin pipe and the like, reducing the number of members related to purge work, reducing the number of work steps at the work and easily fixing a non-blowback system in order to restrict a gas-discharging state to minimum value.SOLUTION: This invention relates to a synthetic resin cap 10 for use in closing an end part of an opened synthetic resin pipe. The synthetic resin cap 10 comprises a connecting part 11 capable of receiving the synthetic resin pipe; and a discharging part 20 for use in performing purging work. The discharging part 20 has a purge hole 30 for discharging air remained in the synthetic resin pipe. The connecting part 11 and the discharging part 20 are arranged so as to cause an axis of the connecting part 11 and an axis of the discharging part 20 to cross each other. |
