Interlocking device for shift rod in power transmission

An interlocking device for a transmission operating rod in a power transmission mechanism of a type, wherein the sliding direction of a shift fork shaft intersects with the axial line of the power transmission operating rod, said interlocking device comprising, in combination:

• (a) a supporting frame in the form of a letter "U" fitted at the lower part of a power transmission casing;
• (b) a guide shaft fixed on said U-shaped supporting frame with the axial center thereof being disposed in the same direction as the sliding direction of said shift fork shaft;
• (c) a shift shaft supported on said guide shaft in a slidable and rotatable manner;
• (d) a selector having an interlocking mechanism which rotates together with the shift shaft, and is rotatably supported on said guide shaft which permits slide-movement of said shift shaft;
• (e) a selection lever rotatably supported on said U-shaped supporting frame, one end of which is connected with said power transmission operating rod, and the other end of which is connected with said selector;
• (f) a shift lever rotatably supported on said U-shaped supporting frame, one end of which is connected with said power transmission operating rod, and the other end of which is connected with said shift shaft;
• (g) cam faces formed on the end surface of said U-shaped supporting frame;
• (h) a steel ball rotatably fitted in a hole perforated in said selection lever at a position confronting to said cam faces;
• and
• (i) a leaf spring provided on said selection lever, and to press-contact said steel ball to said cam faces.
