PROBLEM TO BE SOLVED: To provide a switch mechanism that is used in a movement device for a member to be slid such as a walk-in device for a vehicular seat.SOLUTION: The switch mechanism comprises: a spring member 41 that has plate springs 41a and 41b such as flat power springs or constant load springs, a winding drum 41c to be wound with the plate springs 41a and 41b, and a spring case 41d having a spring storage part 41e for storing the plate springs opened; a switch member 45b; and a switch activating member 41f which is interlocked with the switch member 45b, can enter and advance into the spring storage part 41e and is energized in the entering direction. When the plate springs 41a and 41b are opened, the plate springs 41a and 41b stored in the spring storage part 41e allows the switch activating member 41f to advance, and when the plate springs 41a and 41b are wound up around the winding drum 41c, the switch activating member 41f advances, so that the switch member 45b is switched between On and OFF.SELECTED DRAWING: Figure 7

    【課題】車両シートのウォークイン装置等の被スライド部材移動装置において、使用されるスイッチ機構を提供する。【解決手段】ぜんまいばね又は定荷重ばね等の板ばね41a、41bと、板ばね41a、41bが巻きつけられる巻取ドラム41cと、開放した板ばねを収容するばね収容部41eを有するばねケース41dと、を有するばね部材41と、スイッチ部材45bと、スイッチ部材45bと連動してなり、ばね収容部41eへ進入進出可能であってかつ進入方向へ付勢されたスイッチ起動部材41fと、を備え、板ばね41a、41bが開放されることによりばね収容部41eに収容された板ばね41a、41bによって、スイッチ起動部材41fが進出し、板ばね41a、41bが巻取ドラム41cに巻き取られることでスイッチ起動部材41fが進入することにより、スイッチ部材45bのオン/オフを切り替える。【選択図】図7
