Below, the assembling with respect to upper rall 20 of the force application component 60 that constitutes and control lever 70 is described in this wise.At first, under with the state of rotating shaft 62 in two through hole 73a of two through hole 63b of the union body carriage 63 that is fixed with union body 64 and support 73, this rotating shaft 62 is pressed among two through hole 61c of union body supporting member 61 and fixes.Thus, union body 64 and control lever 70 by with rotating shaft 62 for the center of fascinating be supported on the union body supporting member 61.
Then, as shown in Figure 7, the U font force section 65a fastening that makes elastic component 65 is in the connecting part 72 of control lever 70, and, two support 65b of elastic component 65 are clamped between the lower surface of upper wall 21 of the upper surface of connecting part 61b of union body supporting member 61 and upper rall 20, thereby force application component 60 is inserted in the upper rall 20.Then, make the 61e of resilient clamp portion of the connecting part 61b of union body supporting member 61 be sticked in upper wall 21, and, make the grooving sheet 61d of union body supporting member 61 be sticked in the engagement section of two sidewalls 22.
Thus, force application component 60 and control lever 70 are assembled on the upper rall 20.At this moment, the connecting part 72 of control lever 70 is suppressed it to the anti-release direction fascinate (with reference to Fig. 7) of fascinating by the U font force section 65a application of force of elastic component 65.And, the upper surface of the rake 56 of the lower surface of the link piece 64c of union body 64 and locking component 50 connect (with reference to Fig. 7).
(A) of Fig. 9 is the cutaway view of the lock-out state of expression locking component 50 in the cross section of dissecing along 9-9 line shown in Figure 3, and (B) of Fig. 9 is the cutaway view of the released state of expression locking component 50.
In the seat sliding apparatus 10 that constitutes as described above, under the state of the handle part 71 of inoperation control lever 70, the application force of locking component 50 locked springs 57 is the middle mind-set locking rotation direction application of force with center of turn L, keeps any five states that notch fastens among each notch 35a of each notch 22a, 23a of each lock pawl 55 and upper rall 20 and lower guide 30.Thus, upper rall 20 is locked into can't relatively move (with reference to (A) of Fig. 9) with lower guide 30.
Under the state by 50 lockings of this locking component, when the handle part 71 of operating operation bar 70 was moved upward it, the support 73 of control lever 70 fascinated for middle heart with rotating shaft 62.When the support 73 that is fascinated in this wise at union body carriage 63 pushed downwards, this union body carriage 63 fascinated for middle mind-set makes the mobile direction in its side direction opposite with control lever below (release fascinate direction) with rotating shaft 62.
The link piece 64c that is fixed in the union body 64 on the union body carriage 63 that fascinates in this wise at the rake 56 of locking component 50 is downwards during the application of force, and revolving member 50b is that the clockwise direction (release rotation direction) among (B) of middle mind-set Fig. 9 rotates with center of turn L.Thus, each lock pawl 55 is disengaged with each notch 22a, the 23a of upper rall 20 and the engaging of each notch 35a of lower guide 30, and upper rall 20 becomes the released state that can relatively move with lower guide 30.
At this moment, since revolving member 50b form the slotted hole 54a that constitutes center of turn L and lock pawl 55 away from, therefore, compare with the situation that lock pawl 55 is close with slotted hole 54a, the rake 56 mobile quantitative change downwards of the revolving member 50b that the operation of control lever 70 is correspondingly moved during with release is big.
In addition, since be by union body 64 link piece 64c to revolving member 50b with slotted hole 54a mutually remotely rake 56 application of forces of formation to make this revolving member 50b be that the center turns to released state (Fig. 9 (B)) from locking state (Fig. 9 (A)) with center of turn L, therefore, with near the situation of the position application of force the slotted hole 54a of revolving member 50b is compared, the rake 56 mobile quantitative change downwards of the revolving member 50b that the operation of control lever 70 is correspondingly moved during with release is big.
