Abstract
Official abstract text for this publication.
A meshing-type engagement device includes a first member, a second member, a pressing mechanism, and a reaction force mechanism. The first member is provided with a plurality of first dog teeth. The second member is provided with a plurality of second dog teeth. The pressing mechanism is configured to press the first member to the second member side. The reaction force mechanism is configured to generate a reaction force with respect to a pressing force pressing the first member for the first dog teeth and the second dog teeth to mesh with each other such that the amount of increase in the reaction force with respect to a movement of the first member is larger at a position further on the second member side than a predetermined position compared to the amount of increase to the predetermined position when the first member is pressed.
First claim
Opening claim text (preview).
What is claimed is: 1 . A meshing-type engagement device comprising: a first member provided with a plurality of first dog teeth, the plurality of first dog teeth being placed at regular intervals in a circumferential direction of the first member; a second member provided with a plurality of second dog teeth, the plurality of second dog teeth being placed at regular intervals in a circumferential direction of the second member; a pressing mechanism configured to press the first member to the second member side such that the first dog teeth are inserted between and mesh with the second dog teeth when the first member is pressed; and a reaction force mechanism configured to generate a reaction force with respect to a pressing force pressing the first member for the first dog teeth and the second dog teeth to mesh with each other such that an amount of increase in the reaction force with respect to a movement of the first member is larger at a position further on the second member side than a predetermined position compared to the amount of increase to the predetermined position when the first member is pressed, the predetermined position being a position achieved until the respective dog teeth begin to mesh with each other after the first member is pressed and begins to be moved toward the second member side. 2 . The meshing-type engagement device according to claim 1 , wherein the reaction force mechanism includes a first elastic member causing an elastic force to act on the first member regardless of the position of the first member and a second elastic member in contact with the first member and causing an elastic force to act on the first member in a case where the first member is moved to the predetermined position.
