Sheath structure of bicycle grip

Sheath structure of bicycle grip, comprising an outer sleeve, an inner tube, a bolt, a spring washer and a nut, the outer sleeve being made of softer material such as rubber, the inner tube being made of harder material such as plastic material, said sheath structure being characterized in that:

• the outer sleeve is cut with several transverse slots at equal intervals, an inner end of the outer sleeve being formed with a thinner snapping skirt section;
• and
• the inner tube has an inner diameter slightly larger than the outer diameter of the grip, an outer end of the inner tube being formed with an annular binding rib with larger diameter, the binding rib and an outer end section of the inner tube being cut with a resilient split, the binding rib being further formed with two projecting locking blocks on two sides of the resilient split, each locking block being formed with a stepped embedding hole, a middle portion of the outer circumference of the inner tube being formed with a convex face corresponding to the curvature of a palm, the inner tube being formed with an annular snapping rib near the inner end thereof, the snapping rib having a larger diameter, the inner end of the inner tube being formed with an annular stop rib with even larger diameter, whereby the outer sleeve is fitted around the inner tube with the snapping skirt section firmly fitted on the snapping rib of the inner tube and snapping the same, the outer sleeve being stopped by the stop rib of the inner tube, the inner tube with the outer sleeve being fitted onto an end of the grip, the spring washer being fitted around the bolt which is then passed through the embedding hole of the inner tube to be screwed with the nut.
