<p>PROBLEM TO BE SOLVED: To provide a safe parking device which is not unlocked easily but can be locked securely, is unlikely to be damaged or destroyed, etc., allows easy maintenance, and eliminates the danger of parts of the body or similar objects being caught. SOLUTION: A drive mechanism 2 includes a slide cam 23 having an inclined cam groove 23A and a horizontal groove 23B and engaged with a feed screw 22 rotated by a motor 21; a moving cam 25 mounted in the horizontal groove 23B; a lever 24 that turns when engaged with time inclined cam groove 23A and the moving cam 25; an upper limit sensor 6 which, in order to stop a flap 5 at a certain height, detects the position of the moving cam 25 that moves back; and a lower limit sensor 7 which, in order to depress the flap 5 to its initial position, detects the position of the slide cam 23 that moves back. The parking device also includes a clutch mechanism by which the overload applied to the flap 5 is not transmitted to the drive mechanism 2 and a free connecting mechanism 4 by which the transmission of driving forces from the drive mechanism 2 to the flap 5 is given degrees of freedom regarding positions, the flap 5 being raised and lowered by the motor 21.</p> |
