摘要

The invention provides a foreign matter removing device for use in turnout, and a method for installing a foreign matter removing device for use in turnout. The foreign matter removing device (Y1) which is provided with a basic rail (100) and a sharp rail (200) comprises the components of a guiding-in side component (4) which is provided with a guiding-in flow path (44) and extends along the width direction of the basic rail (100) below the bottom surface (B1) of the basic rail (100); and a connecting part (22) which is provided with a communicating flow path (22c) for communicating a nozzle part (21) with the guiding-in flow path (44). The nozzle part (21) is used for ejecting a medium for eliminating the foreign matter between the basic rail (100) and the sharp rail (200). The connecting part (22) is connected with one end (41) of the guiding-in side component (4) in an area below the bottom surface (B1) of the basic rail (100). The other end (42) of the guiding-in side component (4) outside the bottom surface (B1) of the basic rail (100) in overlook can perform an operation for keeping one end (41) on the connecting part (22) in an anti-disengagement state.
