  By the way, in the assembly structure of each operation lever, both the operation lever and the elastic body in Patent Document 1 are metal parts, and both the loop handle and the holder that are operation levers in Patent Document 2 are also metal parts. Yes, each is assembled with some gaps. For this reason, when operating the operating lever, an abnormal noise is generated in which the operating lever and the support member (elastic body, holder) that supports the operating lever so that it can tilt are displaced at the contact portion. Problem arises.

  Further, in Patent Document 1, the portion of the elastic member that engages with the distal end portion of the operation lever is in contact with the upper rail when the lock mechanism is in the locked state, and is separated from the upper rail when the lock mechanism is in the unlocked state. In Patent Document 2, a return spring is provided to urge the operation lever so that the operation lever is returned to the original position after the operation lever is operated. A predetermined part of the lever comes into contact with a predetermined holding member. Then, the predetermined portion of the operation lever contacts the predetermined holding member when the lock mechanism is in the locked state, and is separated from the predetermined holding member when the lock mechanism is in the unlocked state.

  For this reason, the support member (elastic body, holder) that supports the operation lever so as to be tiltable is replaced with another component (upper rail, predetermined holding member) by repeating the locked state and the unlocked state according to the operation of the operation lever. On the other hand, contact and separation are repeated, and there is a problem that abnormal noise is generated at the time of contact.

The present invention has been made to solve the above-described problems, and an object of the present invention is to provide a seat slide device that can suppress the generation of abnormal noise caused by operation of an operation member.
Another object of the present invention is to provide a seat slide device capable of improving the assembly workability.

  In order to achieve the above object, in the seat slide device according to claim 1, the lower rail member (30) fixed to the vehicle body (B) and the lower rail member fixed to the seat (S) are provided. An upper rail member (20) that is slidable relative to the lower rail member, a lock member (50) that locks the lower rail member and the upper rail member so as not to move relative to each other, and a lock state and a lock state of the lock member. A seat slide device comprising: an operating member (80) that switches between a unlocking state to be released; and a support member (70) that is disposed in the upper rail member and supports the operating member to be tiltable on the upper rail member. The support member is rotatably supported in the insertion holes (22b) of the side walls (22) of the upper rail member. A resin shaft portion (71b) and an elastic member (72) formed with two contact portions (72c) that contact the upper wall (21) of the upper rail member before and after a direction perpendicular to the shaft portion. And a technical feature thereof.

  In the first aspect of the present invention, the support member is disposed in the upper rail member and supports the operation member on the upper rail member so as to be tiltable. The support member is rotatably supported by being press-fitted into the insertion holes on both side walls of the upper rail member with a resin shaft portion, for example, without a gap, and the two contact members of the elastic member are supported. The contact portion is in contact with the upper wall of the upper rail member in the front and rear direction perpendicular to the shaft portion.

  As described above, since the support member is rotatably supported by the both side walls of the upper rail member with the resin shaft portion, the support member rotates when the operation member is tilted by the operation of the operation member. Even so, there is no noise that rubs the metal.

In addition, since the support member is in contact with the upper wall of the upper rail member in the direction perpendicular to the shaft portion with the two contact portions of the elastic member, the support member is rotated by the elastic action of the elastic member. The movement is moderately suppressed. Further, even when the support member is rotated as the operation member is tilted by the operation of the operation member, the two abutting portions, which are elastic members, make contact with the upper wall of the upper rail member due to their elastic action. Maintain contact. For this reason, the abutment portion repeatedly abuts and separates from the upper wall by the operation of the operation member, so that no abnormal noise is generated.
Therefore, generation | occurrence | production of the noise resulting from operation of an operation member can be suppressed.

  Also, the support member can be pivotably supported on the upper rail member simply by press-fitting the shaft portion of the support member into the insertion holes on both side walls of the upper rail member, so that the operation member can be tilted to the upper rail member. Assembling workability is improved.

  Further, since the two contact portions are only in contact with the upper wall of the upper rail member, a predetermined connecting portion of the support member is fixed to the upper rail member so as not to be relatively movable, and the rotation of the support member is suppressed. Compared to the case, the assembling workability for assembling the operation member to the upper rail member so as to be tiltable is further improved.

  Furthermore, since the support member is moderately restrained from rotating by the elastic action of the elastic member, the operation member can be assembled at a predetermined position even if the operation member is twisted or distorted. Assembling workability for assembling to the upper rail member so as to be tiltable is further improved.

  In the invention of claim 2, the support member is formed with an insertion hole for inserting the operation member, and an engagement hole communicating with the insertion hole and corresponding to the engagement hole provided in the operation member. . The support member includes an elastic member that engages with both the engagement hole of the support member and the engagement hole of the operation member.

  The operating member is engaged with the engaging hole of the supporting member after the elastic member is engaged, and the elastic member is inserted into the engaging hole of the supporting member through the engaging hole of the supporting member. By being engaged, it is fixed to the support member. As a result, the operation member can be easily fixed to the support member with a simple configuration, so that the assembly workability of assembling the operation member to the upper rail member so as to be tiltable can be further improved.

The plate-like spring member 72 is fitted to the holder main body 71 by engaging the engagement hole 72d provided in the portion with the cylindrical portion 71e of the holder main body 71 (see FIG. 6).

  The elastic member 73 is formed so as to be close to the both end vicinity portions 73a of the wire-like urging member bent in a U shape (see FIG. 4).

  The operating lever 80 includes a gripping portion 81 disposed outside the upper rail 20, two tilting portions 82 that extend in parallel from both ends of the gripping portion 81 and are disposed in the upper rail 20, and these tilting motions. A distal end portion 83 formed on the distal end side of the portion 82 and having a smaller diameter than the tilting portion 82 (see FIGS. 1 and 2).

  As shown in FIG. 4, the lock member 50 configured as described above is configured so that the tip ends of both support pieces 54 protrude outward from both openings 25 of the upper rail 20. Both end portions 61 of the urging member 60 are engaged with the engaging holes 54b, respectively, and assembled to the upper rail 20.

  At this time, the lock member 50 has the urging member 60 attached to an R shape in which the shaft portions 54a of the both support pieces 54 are formed at the connecting portion (hereinafter also referred to as the inner corner wall 26) between the upper wall 21 and the side wall 22. By being pressed with force, the upper rail 20 is rotatably supported along the R shape of the inner corner wall 26 so as to switch between the locked state and the unlocked state.

  Further, the lock member 50 is moved in a direction in which each lock claw 52 is engaged with each notch 22a, 23a of the upper rail 20 and each notch 35a of the lower rail 30 (hereinafter referred to as a lock direction) by the urging force of the urging member 60. It is energized.

  In addition, as shown in FIG. 3, the holder 70 has both insertion portions 22 b provided at predetermined positions on both side walls 22 of the upper rail 20 with both shaft portions 71 b of the holder main body 71 fitted with the plate spring members 72. For example, it is supported by the upper rail 20 so as to be rotatable by press-fitting in a state where there is no gap.

  At this time, both the abutting portions 72c of the plate-like spring member 72 abut on the upper wall 21 in the direction perpendicular to the both shaft portions 71b of the holder main body 71 to exert an elastic action, whereby the holder main body 71 is The through hole 71a is biased so as to be parallel to the upper wall 21. In addition, the elastic member 73 is assembled so that the portions 73 a near both ends thereof engage with both slits 71 d of the holder main body 71.

  When the tilting portion 82 and the tip portion 83 of the operation lever 80 are inserted into the through hole 71a of the holder main body 71 of the holder 70, the portions 73a in the vicinity of both ends of the elastic member 73 are slit 71d by the elastic action at a predetermined insertion position. The tilting portion 82 is fixed to the holder main body 71 so as not to be relatively movable by engaging with both notches 82 a of the tilting portion 82 via. As a result, the operation lever 80 is supported by the upper rail 20 via the holder 70 so as to be tiltable. At that time, the tip 83 abuts against the abutment 51 of the lock member 50 (see FIG. 3).

7A is a cross-sectional view showing a locked state by the lock member 50 at a cut surface corresponding to the line 7-7 shown in FIG. 3, and FIG. 7B shows a unlocked state by the lock member 50. It is sectional drawing.
In the seat slide device 10 configured as described above, when the gripping portion 81 of the operation lever 80 is not operated, the lock member 50 is centered on the shaft portions 54a of the two support pieces 54 by the biasing force of the biasing member 60. The lock claw 52 is biased in the locking direction, and maintains a state in which each lock claw 52 is engaged with any one of the notches 22 a and 23 a of the upper rail 20 and the notches 35 a of the lower rail 30. As a result, the upper rail 20 and the lower rail 30 are locked so as not to move relative to each other (see FIG. 7A).

  When the gripping portion 81 of the operation lever 80 is operated so as to move upward in such a locked state by the lock member 50, the tilting portion 82 of the operation lever 80 together with the holder main body of the holder 70 has both shaft portions 71b. The tip 83 is tilted to move downward about the center.

  The shaft portions of the two support pieces 54 are pressed against the R shape of the inner corner wall 26 when the abutment portion 51 of the lock member 50 is urged downward by the tip 83 moving downward. It rotates in the anti-lock direction α around 54a (see FIG. 7B). As a result, the engagement of each lock claw 52 with each notch 22a, 23a of the upper rail 20 and each notch 35a of the lower rail 30 is released, so that the upper rail 20 and the lower rail 30 can move relative to each other. Become.

  Then, after the relative position between the upper rail 20 and the lower rail 30 is adjusted, when the gripping portion 81 of the operating lever 80 is moved downward so as to return to the original position, the tip portion 83 biases the contact portion 51. When the lock member 50 is released, the lock member 50 rotates in the lock direction around the shaft portions 54 a of the support pieces 54 by the biasing force of the biasing member 60. Thereby, each lock claw 52 engages with any one of the notches 22a and 23a of the upper rail 20 and each of the notches 35a of the lower rail 30, so that the upper rail 20 and the lower rail 30 cannot be relatively moved again. (See FIG. 7A).

  As described above, in the seat slide device 10 according to the present embodiment, the holder 70 is disposed in the upper rail 20 and supports both the tilting portions 82 of the operation lever 80 to be tiltable on the upper rail 20. . The holder 70 is pivoted to the upper rail 20 by being press-fitted into the insertion holes 22b of the both side walls 22 of the upper rail 20 with both shaft portions 71b of the resin holder main body 71, for example, without a gap. In addition to being supported, the two abutting portions 72c of the plate-like spring member 72 are in contact with the upper wall 21 of the upper rail 20 at the front and rear in the direction perpendicular to the shaft portions 71b of the holder body 71.

  In this manner, the holder 70 is rotatably supported on the both side walls 22 of the upper rail 20 by the both shaft portions 71b of the resin holder body 71, so that the tilting portions 82 are tilted by the operation of the operation lever 80. Accordingly, even when the holder main body 71 is rotated, no abnormal noise is generated that causes the metal to rub.

Further, since the holder 70 is in contact with the upper wall 21 of the upper rail 20 in the direction perpendicular to both shaft portions 71b of the holder main body 71 with both contact portions 72c of the plate spring member 72, the plate 70 The rotation of the holder 70 is moderately suppressed by the elastic action of the spring member 72. Further, even when the holder 70 is rotated in accordance with the tilting of the two tilting portions 82 due to the operation of the operation lever 80, the two abutting portions 72 c of the plate spring member 72 are caused by the elastic action of the upper rail 20. The state in contact with the upper wall 21 is maintained. For this reason, by the operation of the operation lever 80, both contact portions 72c are repeatedly brought into contact with and separated from the upper wall 21, and no abnormal noise is generated.
Therefore, it is possible to suppress the generation of abnormal noise caused by the operation of the operation lever 80.

  Further, the holder 70 can be rotatably supported on the upper rail 20 by simply press-fitting both shaft portions 71b of the holder main body 71 into the insertion holes 22b of the both side walls 22 of the upper rail 20. Assembling workability to be tiltably assembled to the upper rail 20 is improved.

  Further, since both the abutting portions 72c are only in contact with the upper wall 21 of the upper rail 20, a predetermined connecting portion of the holder 70 is fixed to the upper rail 20 so as not to be relatively movable, and the holder 70 is rotated. Compared with the case where it suppresses, the assembly workability | operativity which assembles the holder 70 to the upper rail 20 so that tilting is possible improves more.

  Further, since the holder 70 is moderately restrained from rotating by the elastic action of the plate-like spring member 72, the holder 70 has a predetermined amount even if the two tilting portions 82 of the operation lever 80 are twisted or distorted. As a result, the assembling workability of assembling the operation lever 80 to the upper rail 20 so as to be tiltable is further improved.

  Further, in the seat slide device 10 according to the present embodiment, the holder main body 71 of the holder 70 communicates with the insertion hole 71a for inserting the tilting portion 82 and the distal end portion 83 of the operation lever 80 and the insertion hole 71a. In addition, a slit 71d corresponding to an engagement hole 82a provided in the tilting portion 82 is formed. The holder 70 includes a clip-like elastic member 73 that engages with both the slit 71 d of the holder main body 71 and the engagement hole 82 a of the tilting portion 82.

  The operating lever 80 engages the elastic member 73 with the slit 71d of the holder main body 71, and then inserts the tilting portion 82 and the distal end portion 83 into the insertion hole 71a of the holder main body 71. By being engaged with the engagement hole 82 a of the tilting part 82 via, the holder main body 71 of the holder 70 is fixed. Thereby, since the operation lever 80 can be easily fixed to the holder 70 with a simple configuration, the assembling workability for assembling the operation lever 80 to the upper rail 20 so as to be tiltable can be further improved.
