Seat sliding device

A seat sliding device that slidably supports a seat, the seat sliding device comprising:

• a fixed-side rail;
• a movable-side rail that is slidable with respect to the fixed-side rail and that is configured to support the seat;
• a lock portion that is displaceable between a restraint position, in which sliding of the movable-side rail with respect to the fixed-side rail is restrained, and a release position, in which such restraint is eliminated;
• a releasing lever that is configured to displace the lock portion to the release position;
• a handle that is coupled to the releasing lever and that is operated by a user;
• a flat spring that couples the handle to the releasing lever and that comprises a body portion of an approximately U-like shape or an approximately J-like shape configured to support the handle, the flat spring comprising a pair of engaging pieces that protrude from the body portion in a direction approximately perpendicular to an extending direction of the handle and that engage with the handle;
• and
• an engagement portion provided to the handle, the engagement portion comprising:
• a first engaged surface that is contactable with the pair of engaging pieces from one extending-direction end side of the handle;
• a second engaged surface that is contactable with the pair of engaging pieces from the other extending-direction end side of the handle;
• and
• a connecting portion that connects the first engaged surface and the second engaged surface to each other,
• wherein the connecting portion connects a central portion of the first engaged surface and a central portion of the second engaged surface to each other in a width direction of the movable-side rail.

• and
• an engagement portion provided to the handle, the engagement portion comprising:
• a first engaged surface that is contactable with the pair of engaging pieces from one extending-direction end side of the handle;
• a second engaged surface that is contactable with the pair of engaging pieces from the other extending-direction end side of the handle;
• and
• a connecting portion that connects the first engaged surface and the second engaged surface to each other,
• wherein the connecting portion has a plate shape, and
• wherein a thickness direction of the connecting portion is parallel to a width direction of the movable-side rail.
