Abstract

PROBLEM TO BE SOLVED: To provide a standby mechanism of such a structure that an initial movement member, a following movement member and coupling members are coupled together rotatably to form a four-link mechanism and springs are installed between the members whereby the following movement member makes relative movement to accumulate the shifting force in the springs until the meshing part on the side with a driven member has a matching phase and the meshing is completed by the accumulated shifting force when the matching phase is obtained. SOLUTION: A standby mechanism is equipped with an initial movement member 3 moved by a shifting force, a following movement member 5 coupled with a driven member through an engagement part, coupling members 7 and 9 to couple the members 3 and 5 together rotatably, and springs 19 and 21 installed between these members. When the initial movement member 3 is moved, the members 3, 5, 7, 9 make relative movement and the springs 19 and 21 are deflected for accumulation of the shifting force until the meshing part on the side with the driven member has a matching phase, and the meshing is established by the accumulated shift force when the matching phase is obtained.

For example, when the shift rod 205 is shifted in the direction of meshing between the sleeve gear and the mating member, the shift fork 207 is connected via the sleeve gear while the phases of the meshing portions are not matched. The received resistance causes the coil spring 211 to bend and a shift force to be stored, and when the phases of the respective meshing portions match, the stored shift force causes the sleeve gear and the mating member to mesh with each other.
