In addition, engaging projection parts 36 projecting in the width direction are provided at one end of the lock lever 31 and insertion holes 37 to which the engaging projection parts 36 are vertically movably inserted are provided at each of sidewall parts 15. In addition, a plurality of engaging holes 38 having an upper opening part with which the engaging projection parts 36 can be detachably engaged based on the rotation of the lock lever 31 are provided on a lower rail 5. Further, the lock lever 31 is protruded in the width direction and has an overhang part 50 facing each sidewall part 15 of the upper rail 6, thereby enabling securing a state where the lock lever 31 can be smoothly detachably engaged with each engaging hole 38. |
