Sliding device

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

• a fixed rail;
• a movable rail to which a seat body of the seat is fixed, the movable rail being slidable relative to the fixed rail;
• a lock plate held by the movable rail, the lock plate being displaceable in a direction substantially orthogonal to a sliding direction, the lock plate being displaced between a locking position where the lock plate engages with the fixed rail and restricts slide of the movable rail and a non-locking position where the restriction of slide is released, and the lock plate having a plate surface that crosses a displacement direction of the lock plate;
• a spring member that applies to the plate surface an elastic force to maintain the lock plate in the locking position, the spring member comprising a spring portion that extends in the sliding direction from the lock plate and has a leading end part fixed to the movable rail;
• and
• a fixing structure for fixing the leading end part in an extending direction of the spring portion to the movable rail, the fixing structure comprising:
• a tapered portion provided in the spring member and formed into an acute angle shape, the tapered portion being fitted into a hole provided in the movable rail;
• and
• a press spring portion that exerts an elastic force to press the tapered portion toward the hole,
• wherein a comb portion is provided in the fixed rail, the comb portion having protrusions and recesses alternately provided in series, and
• wherein the tapered portion is positioned below the comb portion.
