Abstract:
1. A shift lever lock device for vehicular automatic transmission comprising: a lock plate rotatably supported around its rotational center, and urged to rotationally move in a predetermined direction by means of a first urging member; a link plate rotatably supported around said rotational center to move toward said lock plate and move away from said lock plate, said link plate being always urged by a second urging member in the direction which said lock plate is urged by said first urging member; a solenoidal coil provided at said rotational center of said lock plate and said link plate so that said solenoidal coil moves said lock plate in unison with said link plate when the solenoid is energized by establishing a magnetic attraction; a first movable core provided on said lock plate to be magnetized when said solenoidal coil is energized; a second movable core provided on said link plate to form a magnetic circuit with said first movable core when said solenoidal coil is energized; and a lock mechanism provided to engage said first movable core with said second movable core when a shift lever is locked in a locked position, and making said first movable core and said second movable core stick together by means of said magnetic attraction when said solenoidal coil is energized, and rotationally moving said lock plate and said link plate together from said locked position to an unlocked position against urging forces of said first urging member and said second urging member to unlock the said shift lever.
