Abstract: An output member is connected with an input member through three sets of link mechanisms for alteration in attitude. The link mechanism includes end portion link mechanisms on an input side and an output side, respectively, and an intermediate link member. The link mechanism is such that a geometric model of each of the link members expressed by lines represents such a shape as an input side portion and an output side portion relative to a center of the intermediate link member are symmetrical with each other. By actuating two or more sets of the link mechanisms by means of a link mechanism drive source, the attitude of the output member is controlled. Through the inside of an arrangement of the link mechanisms, a flexible wire is provided for transmitting a rotational force in a direction of arrangement of the input and output members.

Abstract: In a shift lever device, a first engagement portion or a second engagement portion of a shift lever is inserted into a first stopping hole or a second stopping hole of a strength gate when the shift lever is turned along a manual transmission hole, thereby stopping the shift lever from turning towards an automatic transmission hole side. In the shift lever, the first engagement portion and the second engagement portion are disposed at the vehicle front side and the vehicle rear side of a support body. An increase in size of the shift lever in the vehicle left-right direction due to the first engagement portion and the second engagement portion can accordingly be suppressed, and the turning rage of the shift lever in the vehicle left-right direction can be made smaller, thereby enabling a reduction in size of the shift lever device in the vehicle left-right direction.

Abstract: A steering device is provided that is capable of facilitating an assembly operation, decreasing the number of parts, and decreasing manufacturing costs. A bottom plate of a stopper is tightened to an outer curved surface of an inner column between a head section and a bulged section of a rivet body. An outside diameter of the rivet body increases to eliminate a gap between a first through-hole and a second through-hole. The stopper remains stationary even when it touches a long hole at a telescopic stroke end and repeatedly receives an impact force. The durability of the stopper improves. There is no need for a nut for fixing the stopper to the inner column. The number of parts decreases to reduce manufacturing costs.
