Abstract: When a strain wave gearing is used in an application for an operation of repeating startup/stopping, an outer-side lubrication portion and an inner-side lubrication portion, which are lubricated using different types of grease, remain in a communicating state without being divided using a seal member or the like. The outer-side lubrication portion is supplied with a much smaller amount of grease than the amount that would be required if used in an application such as a steady operation. Similarly, the inner-side lubrication portion is also supplied with a much smaller amount of grease than the amount that would be required if used in an application such as a steady operation. Essentially, the outer-side lubrication portion and the inner-side lubrication portion can be lubricated appropriately using different types of grease, without the grease becoming mixed.

The steering handle is shiftable in forward and rearward directions to thereby cause corresponding forward and rearward rotation of both of the left and right traction elements. The steering handle is rotatable in clockwise and counterclockwise directions to thereby cause a change in the relative speeds and directions of rotation of the left and right traction elements.

Abstract: In a shift device, when a lock lever is disposed at a restriction position or an intermediate position, a detent groove of a lever is abutted by the lock lever, and pivoting of the lever from a D position toward an S position, and pivoting of the lever from the S position toward the D position, is restricted. However, when the lever is disposed at the D position or the S position, by moving the lock lever to a permitted position, the detent groove does not abut the lock lever and so pivoting of the lever from the D position toward the S position and pivoting of the lever from the S position toward the D position is permitted. Thus, pivoting of the lever from the D position toward the S position and pivoting of the lever from the S position toward the D position can be restricted and permitted.
