PROBLEM TO BE SOLVED: To improve durability of an opening/closing body by preventing accuracy of opening/closing body position control from being reduced.SOLUTION: An opening/closing device comprises an opening/closing body 10 which performs an opening/closing operation between a full opening position and a full closing position, a guide rail 20 which guides the opening/closing body 10 in an opening/closing direction, an origin sensor 35 which senses that the opening/closing body 10 has passed a predetermined origin position, and count means 36 which recognizes a variation of the opening/closing body 10 from the origin position as a count value. In the opening/closing device, the origin position is set closer to a closing direction side than the full opening position and closer to an opening direction side than the full closing position and when there is a sensing signal of the origin sensor, the count value is corrected to an operation origin value indicating the origin position. |
