Abstract: A slide rail by which a conveyance seat is slidably coupled to a floor of a conveyance includes: a lower rail attached on the floor; an upper rail slidably assembled to the lower rail and attached to the conveyance seat; and a locking spring supported by the upper rail and having a locking piece that is inserted into a locking slit formed in the lower rail to prohibit the upper rail and the lower rail from sliding relative to each other. The locking piece extends in a direction along a cross-section (the width direction) of the upper rail from a position in the locking spring, at which the locking spring is supported by the upper rail. The locking piece is inserted into the locking slit by deflection deformation of the locking piece in an in-plane direction of the cross-section (the height direction) of the upper rail.
