Abstract:
1. A lid device, comprising: a lid body, which moves between an open position for opening an opening of a storage structure and a closed position for closing said opening of said storage structure; a guide portion formed on said storage structure; and an urging member having one end fixed to said lid body so as to be held by said lid body and the other end engaging and guided by said guide portion so as to be stretched or compressed and thereby accumulate an urging force in association with opening and closing movements of said lid body, wherein the fixed end of the urging member follows a fixed end path when said lid body is moved between the open and closed positions; said urging force drives at least an opening operation of said lid body, said guide portion comprises a closed end portion in which said engaging end is placed when said lid body is placed in said closed position; an open end portion in which said engaging end is placed when said lid body is placed in said open position; a first guide portion connecting said closed end portion and said open end portion and guiding said engaging end when said lid body moves from said closed position to said open position; and a second guide portion connecting said closed end portion and said open end portion and guiding said engaging end when said lid body moves from said open position to said closed position; said first guide portion comprises an initial guide portion connected to said closed end portion, a later guide portion connected to said open end portion; and a connecting portion connecting said initial guide portion and said later guide portion; the second guide portion comprises an accumulating portion, which is connected to the open end portion; a closing guide portion, which is connected to the closed end portion; and an inflection portion, which is connected to the accumulating portion and the closing guide portion; said urging member releases a larger urging force when said engaging end is guided by said initial guide portion than when said engaging end is guided by said later guide portion; a minimum distance between the fixed end path and the open end portion is less than a minimum distance between the fixed end path and the closed end portion; and a minimum distance between the fixed end path and the closed end portion is less than a minimum distance between the fixed end path and the inflection portion.
