<P>PROBLEM TO BE SOLVED: To secure a required insulation distance, and to prevent short-circuiting between electric train lines (live parts) and short-circuiting of a vehicle or the other structure members to the live parts by protecting the live parts. <P>SOLUTION: This guide rail 3A includes: a guide rail 31 which is open upward, in which a pair of guide wheels 23 are inserted, and which has a guide groove 31a formed with a pair of guide surfaces 31b located on both sides of a travel path in the width direction thereof for rolling each of the pair of guide wheels 23 thereon; electric train lines 32 which are arranged on both outer sides of the guide grooves 31a in the width direction of a travel path and against which power collector shoes 43 of power collector devices 4 of a track-based vehicle are pressed so that contact power feed is performed; first insulators 33 each formed of an insulation material and supporting the electric train lines 32 relative to the guide rail; and insulation plates 34 arranged on both sides of the electric train lines 32 in the width direction, and arranged in parallel to the electric train lines 32 and in parallel to the pressing direction of the power collector shoes 43 in order to prevent short-circuiting due to contact with the electric train lines 32 in the vertical direction, and each formed of an insulation material. <P>COPYRIGHT: (C)2012,JPO&INPIT |
