An elastic transmission element is part of a strain wave gear. Such strain wave gears are also referred to as Harmonic Drives. The elastic transmission element is also referred to as a flexspline and has an outer toothing (). The elastic transmission element is equipped with at least one strain gauge () for measuring a mechanical strain on the elastic transmission element. The one strain gauge () or the plurality of strain gauges () extends at least as a whole about a circumference of a lateral surface or an axial lateral face of the elastic transmission element.

An electronic flasher system that reduces the ON duty ratio of an intermittent signal inputted to a semiconductor switch device, thereby suppressing electric power imposed on the semiconductor switch device and, hence, heating thereof, in the event of abnormal heating caused in the semiconductor switch device. The flasher system includes a flasher circuit 21A, a semiconductor switch device 21B, and a device-temperature detecting section 21C arranged in one body to constitute a module unit 21. The device-temperature detecting section 21C is connected to the flasher circuit 21A. The flasher circuit 21A transmits an intermittent signal to the semiconductor switch device 21B so that a direction indicator lamp 1R, 1L connected to the semiconductor switch device 21B is caused to turn-signal flash. The device-temperature detecting section 21C detects a temperature of the semiconductor switch device 21B so that, when the temperature becomes high, the ON duty ratio of the intermittent signal is reduced.
