And the front and rear positions of the seat are adjusted by moving the seat-side rail 2 back and forth via a drive unit. The driving unit is rotatably supported by the seat-side rail 2 via a gear box 3 and a bearing member 4, and is driven by an electric motor (not shown) to rotate. And a nut member 7 rotatably screwed into the housing 1 and fitted in a housing 6 fixed to the vehicle body side rail 1.

That is, as shown in FIG. 13, the nut member 7 was fitted into the housing 6 via the elastic member 8 having a shape similar to the housing 6 and having a through hole 8 a through which the screw member 4 penetrated. By the way, in the related art, the through hole 8 a formed in the elastic member 8 for penetrating the screw member 3 has a sufficiently large diameter with respect to the screw member 3, and does not slide on the outer diameter of the screw member 3. It had been.

あった。However, according to such a conventional technique, even when the screw member 5 is stopped, the nut member 7 and the housing 6 maintain the backlash between the nut member 7 and the screw member 5. It is possible to make slight movements without any resistance by this amount, and this slight movement becomes a so-called rattling feeling of the seat as it is (discomfort felt by the occupant due to the slight movement of the seat in a rattling manner). There was a problem that the sitting feeling was impaired.

示すような装置を提案している。When the seat-side rail 2 stops at the front end and the rear end of the stroke, the front and rear end portions of the housing 6, which is a rigid body in any case, collide with a gear box or the like also made of a rigid body. Since the impact due to the collision is transmitted to the seat side to make the occupant feel uncomfortable, there is a problem that a good occupant's feeling of sitting is impaired.
As a technique capable of buffering the impact due to such mechanical engagement, the applicant has previously proposed an apparatus as disclosed in Japanese Utility Model Application No. 4-67007.

1). Thereby, an appropriate frictional resistance is generated between the elastic member (60) and the screw member (41), and the nut member (42) and the housing (50) are relative to the screw member (41). A moderate resistance is added to the simple movement (that is, the back and forth movement of the seat (B)). Therefore, even when the seat (B) slightly moves by the amount of the backlash between the nut member (42) and the screw member (41), such a slight movement becomes a gradual movement and no rattling is caused, and the occupant becomes immobile. There is no pleasure.

0b) has a front edge and a rear edge, respectively.
0), the front and rear ends (51, 52) of the housing (50) are formed as stopper portions (51, 52) when the buffer portions (65, 66) extend along the front and rear ends of the housing (50). Rather than colliding directly with the stopper portions (43, 44), the buffer portions (65, 66) of the elastic member (60) disposed therebetween elastically contact the stopper portions (43, 44).

While being supported within the peripheral edges of the screw members 3 and 54, the screw member 41 contacts the screw member 41 in a wide area. Thereby, an appropriate frictional resistance is generated between the elastic member 60 and the screw member 41, and an appropriate resistance to the relative movement of the nut member 42 and the housing 50 with respect to the screw member 41 (that is, the forward and backward movement of the seat B). Will be added. Therefore, even when the seat B slightly moves by the amount of the backlash between the nut member 42 and the screw member 41, such fine movement becomes a gradual movement and no rattling occurs, and the seating feeling of the occupant is further improved. Can be improved.

As shown in FIG. 9, at the front end of the movement stroke of the nut member 42 with respect to the screw member 41 (the rearmost position of the seat B), the end face (stopper portion) of the gear box 43 collides with the front end 51 of the housing 50. Accordingly, the relative forward movement of the nut member 42 is forcibly restricted.
The rear end of the movement stroke of the nut member 42 (seat B
(The foremost position), the end surface (stopper portion) of the bearing member 44 collides with the rear end portion 52 of the housing 50, whereby the relative rearward movement of the nut member 42 is forcibly restricted.

By forming the front and rear edges of the elastic member 60a as the buffer portions 65 and 66, an unpleasant impact at the time of stoppage can be eliminated without increasing the number of parts and the number of assembling steps, and cost reduction can be sufficiently achieved. it can. In addition, screw member 4
The outer circumference of the first through-hole 1 includes not only the inner circumferences of the through holes 63 and 64 of the elastic member 60a, but also the insertion holes 67 and 68 of the buffer portions 65 and 66.
Is also in sliding contact. Accordingly, the frictional resistance of the elastic member 60a with respect to the screw member 41 is increased, so that it is possible to suppress the feeling of backlash.

A vehicle-side rail, and a seat-side rail which is fitted to the vehicle-side rail so as to be movable in the front-rear direction and supports a seat, and the seat-side rail is moved back and forth by an electric motor via a driving unit. In the power seat slide device for adjusting the front / rear position of the seat, the screw is rotatably supported on one of the vehicle body side rail and the seat side rail, and is rotationally driven by the electric motor. A member, an opening through which the screw member penetrates is formed, and a housing fixed to the other of the vehicle-body-side rail or the seat-side rail, and screwably rotatably screwed to the screw member; A nut member fitted into the housing, and an elastic member having a through hole formed through the screw member and interposed between the nut member and the housing. The peripheral edge of the through-hole of the elastic member forms an annular projection that penetrates through the opening and extends to the outside of the housing, and alleviates the backlash due to the slight movement of the nut member due to the backlash. A power seat slide device, wherein an inner periphery of the through hole is in sliding contact with an outer periphery of the screw member so as to generate frictional resistance.
