There is provided a foreign material removing device of a track turnout portion which can tightly attach and fix nozzles to a rail belly portion stably without machining a rail itself. A foreign material removing device of a track turnout portion which has point rails which can move to contact and move away from stock rails of the track turnout portion, and which removes a foreign material dropped between the stock rail and the point rail, includes a piping unit which includes a plurality of nozzle portions which spray compressed air to remove the foreign material, and the piping unit includes a close-contact arrangement structure in which the piping unit is arranged in close contact with a lateral surface of the stock rail opposed to the point rail.

Foreign material removing device of track turnout portion

Provided is a foreign matter removing apparatus at a track branch, and a nozzle used in this apparatus that are capable of sufficiently securing foreign matter removing performance as well as significantly reducing generation of noises. In the nozzle for the foreign matter removing apparatus at a track branch, compressed air supplied from piping is injected from each nozzle element. Slits are formed in each nozzle element, a sloped portion is formed at a front end of the nozzle element, and this sloped portion opposes a tongue rail.
