Each locking portion 21C is a protruding portion on which the corresponding locked portion 22C is caught.

<Fixing structure of the first cable guide>
As shown in FIG. 8, the first cable guide 20 is provided with a recess 20A. As shown in FIG. 4, the recess 20A is a recess into which at least a portion of the frame 2A can fit.

When the first cable guide 20 is fitted into the recess 20A into the frame 2A, displacement of the first cable guide 20 in the longitudinal direction of the fixed rail 11 is restricted. That is, the recessed portion 20A constitutes an example of a positioning portion that determines the position of the first cable guide 20 in the longitudinal direction.

As shown in FIG. 8, the first cable guide 20 is provided with at least one (in this embodiment, two) protrusions 20B. Each protrusion 20B is a part that is fitted into a hole (not shown) provided in the frame 2A.

<Second cable guide>
As shown in FIG. 4, the second cable guide 30 is a member that slides into contact with the lower end portion 7B of the cable 7, thereby regulating the vertical position of the lower end portion 7B. As shown in FIG. 9, the vertical position is a position above the lower end 11C of the first wall 11A of the fixed rail 11 and the lower end 11D of the second wall 11B.

The lower end portion 7B refers to the lower end portion of the cable 7 that extends from above the fixed rail 11 toward the fixed rail 11, as shown in FIG. In other words, the lower end portion 7B is a portion of the cable 7 whose extension direction changes from a substantially vertical direction to a substantially horizontal direction.

A portion 7C (see FIG. 2) of the cable 7 extending from the lower end portion 7B to the longitudinal end side of the fixed rail 11 is located within the fixed rail 11. In other words, the portion 7C is located within the space 11E sandwiched between the first wall portion 11A and the second wall portion 11B.

As shown in FIG. 9, the first wall portion 11A and the second wall portion 11B are wall portions that are substantially parallel to the vertical direction and face each other across the space 11E in the width direction. The first wall portion 11A and the second wall portion 11B are band-shaped portions that extend along the longitudinal direction of the fixed rail 11.

The space 11E is a part where a part of the movable rail 12 is located. Therefore, in the region where the movable rail 12 is located, the first wall portion 11A and the second wall portion 11B face each other with the movable rail 12 in between. Note that the width direction refers to a horizontal direction orthogonal to the longitudinal direction of the fixed rail 11.

The movable rail 12 is provided with a guide fixing portion 40, as shown in FIG. The guide fixing part 40 is a member that is located within the fixed rail 11 and is fixed to the movable rail 12 so as to be displaced together with the movable rail 12.

The recessed portion 12A is provided at one end and the other end in the width direction of the movable rail 12. The convex portion 41 is provided at a position corresponding to each of the two concave portions 12A.

The guide fixing part 40 is fixed to the movable rail 12 so as to sandwich the movable rail 12 from the width direction with each convex part 41 fitted into each concave part 12A. In other words, each convex portion 41 engages with each concave portion 12A, so that the guide fixed portion 40 and the movable rail 12 are displaced as one unit.

The second cable guide 30 is fixed to a guide fixing part 40. That is, as shown in FIGS. 11 and 12, a locking portion 31 is provided on the bottom surface of the second cable guide 30. A locking portion 42 is provided in a placing portion 42A of the guide fixing portion 40 on which the second cable guide 30 is placed.

Note that the plurality of protrusions 33A and 33B are continuously provided over the entire area from one end of the through hole 32 to the other end.

The plurality of protrusions 33A slide into contact with the upper surface of the cable 7 and guide the movement of the cable 7. The plurality of protrusions 33B slide into contact with the lower surface of the cable 7 and guide the movement of the cable 7. Note that when the cable 7 moves, tension is applied to the cable 7, so in many cases, the plurality of protrusions 33A come into contact with the cable 7.

<3. Features of the vehicle seat according to this embodiment>
In the vehicle seat 1 according to the present embodiment, as shown in FIG. 3, the cable reel 15 projected on the virtual horizontal plane overlaps with the seat body 2 projected on the horizontal plane, and the cable reel 15 is projected on the horizontal plane.

Therefore, in the vehicle seat 1, an increase in the number of assembly steps can be suppressed.

The second cable guide 30 has at least one protrusion 33A that slides into contact with the upper surface of the cable 7 and guides the movement of the cable 7. As a result, the contact area between the second cable guide 30 and the cable 7 becomes smaller, so that slip resistance when the cable 7 moves can be suppressed.
