PROBLEM TO BE SOLVED: To provide an electrically-driven automatic door having a stable opening/closing speed by preparing a power transmission method in a variable type, in consideration of the fact that a load by action and the self-weight of a user are limited, the door may not be opened, and unstable operation of the door occurs such as faster or slower opening/closing speed due to individual difference of users.SOLUTION: A mat 2 as means for taking in the kinetic energy without use of electric power is traversed so that a rack 34 incorporated in the mat 2 is engaged with a gear 32 as an intermediate rotor; the gear 32 and a pulley 33 as an output rotor rotate coaxially and integrally; and the pulley 33 is installed asymmetrically with respect to a revolving shaft, transmits kinetic energy to a wire 35, a belt, and an output part to open/close a connected door. |
