  • each tip 61 urged and held by the torsion spring 41 in the support groove 62 is positioned in such a manner that its upper surface abuts against the opposing surface of the support wall 22 (upper edge 22a).
  • the pressing portion 63 is disposed above the input portion 33 of the locking member 30 with a space therebetween. Accordingly, the locking member 30 released from the distal end portion 61 (the release handle 6) is inserted into the locking hole 13a and the fitting direction in which the locking portion 34 is lowered by the torsion spring 41, that is, the locking claws 34b to 34d. It is biased toward the direction of fitting into the groove 16a.
  • the relative movements of the lower rail 3 and the upper rail 4 are appropriately regulated by fitting the locking claws 34b to 34d into the corresponding lock holes 13a and the fitting grooves 16a. And the position of the front-back direction of the sheet
  • each distal end portion 61 rotates in the direction in which the pressing portion 63 is lowered with the support point O1 as a fulcrum, thereby pressing the input portion 33 of the locking member 30 with the pressing portion 63. Accordingly, the locking member 30 is moved in a direction in which the locking portion 34 rises around the shaft portion 32 against the urging force of the torsion spring 41, that is, in a direction in which the locking claws 34b to 34d are released from the corresponding lock holes 13a. Rotate.
  • a cover 50 for closing the first end is attached to the first end, that is, the front end of the upper rail 4, the exposure of the first end is suppressed and the first end is directly connected to the peripheral component. Can be avoided. Further, for example, when the release handle 6 swings about the contact portion (support point O1) with the support wall portion 22 due to vehicle vibration, the release handle 6 is connected to the second connecting wall portion at the first end of the upper rail 4. 15, it comes into contact with the cover 50 (the connecting wall cover portion 52). Therefore, generation
  • the connecting wall cover portion 52 functions as a simple stopper with respect to the input direction at the time of the release operation of the release handle 6, it is possible to suppress the rotation (rattle) in this direction and the generation of abnormal noise resulting therefrom. Yes. Further, when the release handle 6 is rotated against the urging force of the torsion spring 41 to transmit the operation force for releasing the restriction on the relative movement of the lower rail 3 and the upper rail 4 to the locking member 30, the release handle 6 is transmitted. Even if the cover 50 is pressed by this, the rotation of the cover 50 due to the pressing is restricted by the locking piece 56.
  • both the locking pieces 56 function as a stopper for the cover 50 itself with respect to the input direction during the release operation of the release handle 6, so that rotation (rattle) in that direction is suppressed. Therefore, the cover 50 can be prevented from coming off from the first end due to the rotation of the cover 50. That is, while the cover 50 realizes a measure against abnormal noise by bringing the release handle 6 into contact with the cover 50, the cover 50 locks the measure against the disengagement from the first end of the cover 50 when the cover 50 is pressed by the release handle 6. This is realized by the piece 56.
  • the release handle 6 presses the cover 50 with its rotation
  • the release handle 6 makes surface contact with the inclined surface 52a of the cover 50 (the connecting wall cover portion 52) set to the inclination angle at that time.
  • the load at the contact portion with the cover 50 can be dispersed. Therefore, the cover 50 can be prevented from being pressed from the release handle 6 with a concentrated load, and deformation of the cover 50 can be suppressed.
  • the tip (61) of the release handle 6 may be cylindrical. In this case, the distal end portion of the release handle 6 comes into point contact with both sliding beads 57.
  • the extending direction of the sliding bead 57 is arbitrary as long as it intersects the insertion direction of the release handle 6.
  • the support wall part 22 comprised only by the upper edge 22a and the lower edge 22b which omitted the side edges 22c and 22d may be sufficient. That is, the support wall portion 22 does not necessarily have a square frame shape.
  • an urging member made of a leaf spring may be adopted.
  • a biasing member that biases the locking member 30 and a member that holds the release handle 6 (tip portion 61) may be provided separately.
  • the lower rail 3 and the upper rail 4, and the vehicle floor 2 and the seat 5 may be fixed in a fixed relationship (that is, an upper and lower arrangement relationship).
