摘要： A baseplate is adapted to be secured to a rail carrier and formed with a groovelike recess adapted to receive a rail foot of said rail and to hold said rail foot against a lateral movement. Two resilient clamping members are disposed on opposite sides of said recess. Each of said clamping members has two downwardly facing, sharp, pressure-exerting edge portions spaced apart in the longitudinal direction of said recess and overlying the same. Pivotal mounting means connect each of said clamping members to said baseplate for pivotal movement about a predetermined axis in response to a predetermined force acting on said pressureexerting edge portions in the longitudinal direction of said recess. Said pivotal mounting means for each of said clamping members comprise a threaded fastener, which is centered on said axis and extends through said clamping member into said baseplate and retains said clamping member on said baseplate. The rail foot is as wide as said recess and has downwardly and laterally outwardly inclined top surfaces on opposite sides. The threaded fasteners force said pressure-exerting edge portions against said inclined top surfaces so that the latter can exert said force on said pressure-exerting edge portions.
