SLIDING ARMREST

PROBLEM TO BE SOLVED: To solve such a problem that in the prior art, a cover or the like is provided since the looks are horrible, if an edge etc. of a belt-like spring is exposed and movement distance and the extension of a plate spring becomes equal, and the range covered with the cover, etc. broadens, and improvement of the appearance is not easy.SOLUTION: A sliding armrest includes: an armrest body 1, a first base 2, a second base 3, a base body 4, an energizing means 6, and a variable speed drive means 5. The first base 2 and the armrest body 1 are combined. The second base 3 installed on the base body 4 is driven from a first start point to a first end point by the energizing means 6 and becomes movable for a first distance, and the first base 2 becomes movable for the second distance from the second start point to a second end point relative to the second base 3. The variable speed drive means 5 transmits the move between the base body 4 and the second base 3 by accelerating to the move between the second base 3 and the first base 2 and the second distance becomes longer than the first distance.
