Further, the horizontal plate portion 41 of the second plate member 32 is also formed with an opening 41 a through which the roller 33 passes in a portion corresponding to the position where the roller 33 is disposed.

  The rollers 33 are provided on both sides of the support shaft 34 in the longitudinal direction (left-right direction). The rollers 33 and 33 can be constituted by well-known ball bearings. The support shaft 34 is inserted into the inner raceway 33 a of the rollers 33 and 33, and the outer raceway 33 b rotates around the support shaft 34.

  The lower portions of the rollers 33, 33 protrude from the openings 36 a, 41 a of the horizontal plate portions 36, 41 below the horizontal plate portions 36, 41. The raceway 33 b outside the rollers 33, 33 comes into contact with the bottom plate portion 21 of the vehicle body side rail 20 and rolls. Therefore, the rollers 33 and 33 receive the load of the vehicle seat 2.

  A left-side groove 37b is formed at an intermediate portion in the vertical direction of the side plate portion 37 of the first plate material 31 so as to face the left-side groove 22b of the vehicle body side rail 20. The inner surface (rolling surface) of the left groove 37b is formed to be able to roll with the spherical member 50 fitted. The left side groove 37b of the seat side member 30 has a substantially arc-shaped cross section that opens to the left side, and extends in the front-rear direction in parallel with the left side groove 22b of the vehicle body side rail 20. The curvature of the cross section is set similarly to the curvature of the left groove 22b of the vehicle body side rail 20.

  Further, a right groove 42b is formed at an intermediate portion in the vertical direction of the side plate portion 42 of the second plate member 32 so as to face the right groove 23b of the vehicle body side rail 20. The inner surface (rolling surface) of the right groove 42b is formed to be able to roll with the spherical member 50 fitted. The right groove 42b of the seat side member 30 has a substantially arc-shaped cross section that opens to the right, and extends in the front-rear direction in parallel with the right groove 23b of the vehicle body side rail 20. The curvature of the cross section is set similarly to the curvature of the right groove 23b of the vehicle body side rail 20.

  The side plate portion 37 of the first plate material 31 urges the spherical member 50 so as to press-contact the left side groove 37 b of the side plate portion 37 and the left side groove 22 b of the vehicle body side rail 20. That is, the side plate portion 37 is made of a steel plate having elasticity as described above, and is disposed on the left side while being disposed between the left plate portion 22 and the right plate portion 23 inside the vehicle body side rail 20. The spherical member 50 is shaped so as to bias it to the left side. As a result, the spherical member 50 comes into pressure contact with the left groove 22 b of the vehicle body side rail 20, and the spherical member 50 receiving the reaction force comes into pressure contact with the left groove 37 b of the side plate portion 37 of the first plate member 31.

  Similarly, the side plate portion 42 of the second plate member 32 urges the right spherical member 50 to press-contact the right side groove 42 b of the side plate portion 42 and the right side groove 23 b of the vehicle body side rail 20.

  By energizing the spherical member 50 as described above, the spherical member 50 comes into pressure contact with the seat side member 30 from both the left and right sides. It won't stick. Further, since the spherical member 50 is pressed against the seat side member 30 in this manner, the seat side member 30 does not rattle with respect to the vehicle body side rail 20 in the vertical direction.

  That is, the pressure contact force of the spherical member 50 by the side plate portion 37 of the first plate member 31 and the side plate portion 42 of the second plate member 32 suppresses the seat side member 30 from rattling in the vertical direction and the horizontal direction with respect to the vehicle body side rail 20. Is set to be able to.

  Next, the case where the vehicle seat slide device 1 configured as described above is used will be described.

  When adjusting the position of the vehicle seat 2, the occupant uses the operation lever 3a to operate the lock device 3 to bring it into the unlocked state. Thereafter, when a longitudinal force is applied to the vehicle seat 2, the rollers 33, 33 of the seat side member 30 roll on the bottom plate portion 21 of the vehicle body side rail 20, and the seat side member 30, that is, the vehicle seat 2 is moved. It moves in the front-rear direction while being guided by the vehicle body side rail 20.

  When the seat side member 30 moves, the spherical members 50, 50 are only in pressure contact with the left side groove 22b, the right side groove 23b of the vehicle body side rail 20, the left side groove 37b of the side plate portion 37, and the right side groove 42b. It rolls in a state of being pressed against 22b and 37b, and moves smoothly. Therefore, the spherical members 50 and 50 do not hinder the movement of the sheet side member 30.

  When the vehicle seat 2 reaches a predetermined position, the lock device 3 is operated by the operation lever 3a to be locked. Thereby, the seat side member 30, that is, the vehicle seat 2 is fixed to a predetermined position of the vehicle body side rail 20.

  In a state where the vehicle seat 2 is fixed to the vehicle body side rail 20, the spherical members 50, 50 are pressed against the left groove 22b, the right groove 23b, the left groove 37b of the side plate portion 37, and the right groove 42b of the vehicle body side rail 20. Therefore, the seat side member 30 does not rattle with respect to the vehicle body side rail 20 in the vertical direction and the horizontal direction.

  For example, it is conceivable that the spherical member 50 is worn due to secular change, and the vehicle body side rail 20 and the seat side member 30 are slightly deformed. In this embodiment, the spherical member 50 is urged by an elastic force. Therefore, the spherical member 50 can be always kept in pressure contact with the left grooves 22b and 37b and the right grooves 23b and 42b by following the wear of the spherical member 50 and the deformation of each member. Therefore, rattling of the vehicle seat slide device 1 can be suppressed over a long period of time, and a smooth operation can be realized by suppressing the sliding resistance during the seat slide.

  Further, since the side plate portions 37 and 42 as the urging portions are integrally formed with the first plate material 31 and the second plate material 32, respectively, the increase in the number of parts can be suppressed and the cost can be reduced.

  Further, as in Modification 1 shown in FIG. 4, the depths of the left groove 22b and the right groove 23b of the vehicle body side rail 20 may be made deeper than the left groove 37b and the right groove 42b of the seat side member 30. In the first modification, the left groove 37b is formed in a substantially V shape that opens to the left, and the right groove 42b is formed in a substantially V shape that opens to the right. Therefore, the outer surfaces of the spherical members 50 and 50 come into contact with two points on the inner surfaces of the left groove 37b and the right groove 42b, respectively.

  The center line in the left-right direction of the gap between the side plate part 37 and the left plate part 22 is S, and the horizontal distance between the contact point of the spherical member 50 in the left groove 37b of the side plate part 37 and the center line S is Y. When the horizontal distance between the contact point of the spherical member 50 and the center line S in the left groove 22b of the portion 22 is X, the depth of the left grooves 22b and 37b is set so that X is longer than Y. Yes. Further, the depths of the right grooves 23b and 42b are set similarly to the left side.

  Thereby, when the vehicle seat 2 is moved and the spherical member 50 rolls between the left groove 22b and the left groove 37b, the seat side member 30 is more than the moving distance of the spherical member 50 relative to the vehicle body side rail 20. The moving distance with respect to becomes shorter. Therefore, when it is assumed that the length of the sheet side member 30 is the same, the separation distance in the front-rear direction of the spherical member 50 can be increased as compared with the case where X is shorter than Y or X = Y. it can. As a result, rattling can be further suppressed.

  Further, by setting X to be longer than Y, the distance from the rotation center of the spherical member 50 to the contact point to the left groove 22b and the distance from the rotation center of the spherical member 50 to the contact point to the left groove 37b. , The distance to the contact point to the left groove 22b becomes longer. Accordingly, it is possible to secure a large amount of sliding of the sheet side member 30 without increasing the length of the sheet side member 30.

  Further, as in the second modification shown in FIG. 5, the left grooves 22 b and 37 b and the right grooves 23 b and 42 b may be formed above the support shaft 34. Thereby, the spherical member 50 can be positioned above the support shaft 34.

  Further, as in Modification 3 shown in FIG. 6, the left grooves 22 b and 37 b and the right grooves 23 b and 42 b may be formed above the rollers 33 and 33. The left side groove 22 b of the vehicle body side rail 20 is formed in the upper part of the left plate portion 22 of the vehicle body side rail 20. Similarly, the right groove 23b of the vehicle body side rail 20 is formed at the upper portion of the right plate portion 23 of the vehicle body side rail 20.

  The left side groove 37 b of the sheet side member 30 is formed in the upper part of the side plate portion 37. Similarly, the right groove 42b of the sheet side member 30 is formed in the upper part of the side plate portion 42. In this modification, the spherical member 50 can be positioned above the rollers 33, 33 so as to overlap the rollers 33, 33 in plan view, so that the spherical member 50 is compared with the above-described embodiment. The slide device 1 can be arranged closer to the center in the left-right direction, whereby the size in the left-right direction of the vehicle seat slide device 1 can be shortened. Therefore, the freedom degree at the time of mounting the vehicle seat slide apparatus 1 in a vehicle can be improved.

  Moreover, you may make it arrange | position the one roller 33 in the center part of the left-right direction of the vehicle seat slide apparatus 1 like the modification 4 shown in FIG.
