A male threaded member and a female threaded member that engage with each other are provided in the case, and the coil spring is made non-rotatable but slidable with respect to the case by applying a rotational force to one of the male threaded member and the female threaded member. In a timing belt tensioning device that tensions the timing belt by driving the other member to extend and contract, the male threaded member, the female threaded member, and the coil spring are arranged coaxially and so as to overlap each other in the radial direction. Timing belt tension device.
