Patent ID: 8544389

Claim:
A guide rail that is provided in a track and is brought into contact with a guide wheel of a vehicle to restrict a rolling direction of a running wheel of the vehicle, to thereby guide the vehicle along the track, comprising: a rail that includes a guide portion formed with a guide rail surface with which the guide wheel is brought into contact and formed with a back surface on an opposite side thereof; a vibration-isolating member that is provided so as to be in contact with the back surface of the guide portion; and a fixation unit that fixes the vibration-isolating member by pressing against the back surface, wherein the fixation unit comprises a bolt and a nut, wherein the bolt is fixed to the back surface and runs through the vibration-isolating member in a direction normal to the back surface, wherein the nut is screwed on the bolt so as to tighten the vibration-isolating member onto the back surface, wherein a through-hole through which the bolt is inserted penetrates the vibration-isolating member, and wherein a small-diameter hole with a diameter larger than that of the through-hole is formed at a base on a back surface side of the through-hole end facing the back surface of the guide portion, wherein the small-diameter hole accommodates a swell-out portion by deformation of the vibration isolating member.
