Transmission

A transmission comprising:

• an input shaft connected to a prime mover, and supported by a transmission-case member;
• an output shaft arranged parallel to the input shaft and supported by the transmission-case member;
• an input disk which is installed on the input shaft and whose outer peripheral edge is arranged in close proximity to the output shaft;
• an output disk which is installed on the output shaft and whose outer peripheral edge is arranged in close proximity to the input shaft;
• and
• a pair of pressure-application devices configured to be movable along a two-axes connecting line, interconnecting an axis of the input shaft and an axis of the output shaft, within a disk overlapping area that the input and output disks overlap with each other, and further configured to sandwich both outside faces of the input and output disks while applying contact pressure from the outside disk faces at a position corresponding to a required transmission ratio, for creating a torque-transmission contacting portion by elastic deformation of the input and output disks.
