Transmission and meshing clutch

A transmission comprising:

• a meshing clutch that connects one shift stage with meshing and is released when changing connection to another shift stage through simultaneously meshing, wherein
• the meshing clutch is provided with meshing teeth on one side and on another side to perform the meshing,
• a meshing tooth on the one side is provided on one rotary member being axially movable to perform torque transmission at said one shift stage, and a meshing tooth on the other side is provided on another rotary member to perform the torque transmission between said one rotary member and said another rotary member, the meshing tooth on said another side with which the meshing tooth on said one side meshes due to axial movement of said one rotary member,
• a releasing-guide part inclined is provided at a tooth top of any one of the meshing teeth on said one side and on said another side to bring a tooth top of a counterpart into contact with the releasing-guide part according to relative rotation to guide the releasing,
• a moving mechanism generates axial force to move said one rotary member to an axial position at which the contact according to the relative rotation is allowed when the meshing teeth mesh to perform transmission of driving torque, and the moving mechanism releases the axial force according to generation of coasting torque,
• said one rotary member engages and is axially movably supported with a torque transmission member in a rotational direction,
• said another rotary member is relatively rotatably supported and is axially unmovably supported with the torque transmission member,
• an urging mechanism is arranged between said one rotary member and the torque transmission member to urge said one rotary member with force being poorer than the axial force being generated by the moving mechanism so that the meshing teeth mesh due to that said one rotary member moves from a neutral position to said another rotary member,
• the urging mechanism is provided with a contact body and an urging functional part,
• the contact body is arranged in a supporting hole formed on the torque transmission member in a radial direction and is urged by the urging functional part toward an inner periphery of said one rotary member, and
• the inner periphery of said one rotary member is provided with an urging and converting part that receives the contact body being urged in the radial direction by the urging functional part and converts a direction of the urging to the axial direction to urge the axial movement of said one rotary member.
