Abstract:
1. A motion conversion transmission apparatus comprising: an input member, an intermediate member, and an output member which are fitted to one another while being aligned with an axis and move in relation to one another while being aligned with the axis; a first transmission which converts a first motion of the input member to a second motion and transmits the second motion to the intermediate member, the first motion being one of a rectilinear motion along the axis and a rotary motion about the axis, and the second motion being the other of the rectilinear motion along the axis and the rotary motion about the axis; a second transmission which converts the second motion of the intermediate member to the first motion and transmits the first motion to the output member; and at least one of the first transmission and the second transmission continuously and nonlinearly varies a ratio of an amount of motion of a motion transmission destination member to an amount of motion of a motion transmission source member according to the amount of motion of the motion transmission source member, wherein a ratio of an amount of motion of the output member to an amount of motion of the intermediate member is larger than a ratio of an amount of motion of the intermediate member to an amount of motion of the input member.
