Claims

[Claims for Utility Model Registration] 1. A notched groove is formed along the axial direction in one of the inner and outer cylinders that are slidably fitted, and a protrusion that is press-fitted into the notched groove is fixed on the other side. A shock absorbing device for a vehicle, characterized in that the protrusion is formed into a rectangular plate shape along the notch groove and whose width is somewhat larger than the width of the notch groove. 2. The shock absorbing device for a vehicle according to claim 1, wherein four projections are provided at intervals of 90 degrees with respect to the circumferential direction of the cylinder. 3. Forming an introduction part that expands into a flap shape at the inner cylinder insertion end of the outer cylinder, extending the end of the notch groove to the introduction part, and extending the end from the axis of the outer cylinder. 3. The shock absorbing device for a vehicle according to claim 1, wherein the radius is set larger than the radius from the axis of the inner cylinder to the outer end of the projection. 4. The vehicle shock absorber according to claim 1, wherein the protrusion is integrally formed with the tube by burring.
