A steering apparatus comprising: a lower column that can be fixed to a vehicle body by its front side with respect to the vehicle body; an upper column that is fitted to said lower column in such a way as to be able to make collapsing movement or movement frontward with respect to the vehicle body and rotatably supports a steering shaft on which a steering wheel is attached; an upper bracket that can be attached to the vehicle body in such a way that it can be detached forward with respect to the vehicle body together with said upper column by an impact force upon secondary collision; a guide bracket that is fixed to said lower column by its front side with respect to the vehicle body, extends rearward with respect to the vehicle body along said lower column, and has a guide groove that guides the collapsing movement of said upper column upon a secondary collision; and a guide pin that is fixed to said upper bracket and can move with the upper bracket with the outer circumferential surface of its shaft portion being guided by said guide groove, wherein said guide bracket has a flat plate portion that is not in contact with said upper bracket, said flat plate portion (61 d) being provided with said guide groove, and said guide pin has a head portion provided on top of the shaft portion of the guide pin and having a diameter larger than the shaft portion, characterised in that: the steering apparatus comprises a gap setting portion that is in abutment with an upper surface (211 a) of said upper bracket when said guide pin is fixed to said upper bracket to set the length of a gap between a lower surface of said head portion and an upper surface of the upper bracket to a predetermined value; and a spacer (72; 73; 74; 75; 76) made of a synthetic resin that is externally fitted on an outer circumferential surface of the shaft portion of the guide pin and can make collapsing movement or move with its outer circumferential surface being in contact with said guide groove, wherein the outer circumferential surface of said spacer (72; 73; 74; 75; 76) is provided on a cylinder portion (721; 731; 741) or a rectangular cylinder portion (751; 761) provided with two parallel flat portions (755; 765), wherein the cylinder portion (721; 731; 741) or the two flat portions (755; 765) can make collapsing movement or move while being in contact with said guide groove; wherein a flange portion (722; 732; 742; 752; 762) is provided at the top of said spacer (72; 73; 74; 75; 76) and has a diameter larger than the outer circumference of the cylindrical portion (721, 731, 741), or a diameter larger than the rectangular cylinder portion, or has a rectangular shape with sides longer than the sides in contact with said flat plate portion of the rectangular cylinder portion; said head portion of the pin pressing the flange portion (722; 732; 742; 752; 762) of said spacer (72; 73; 74; 75; 76). a lower column that can be fixed to a vehicle body by its front side with respect to the vehicle body; an upper column that is fitted to said lower column in such a way as to be able to make collapsing movement or movement frontward with respect to the vehicle body and rotatably supports a steering shaft on which a steering wheel is attached; an upper bracket that can be attached to the vehicle body in such a way that it can be detached forward with respect to the vehicle body together with said upper column by an impact force upon secondary collision; a guide bracket that is fixed to said lower column by its front side with respect to the vehicle body, extends rearward with respect to the vehicle body along said lower column, and has a guide groove that guides the collapsing movement of said upper column upon a secondary collision; and a guide pin that is fixed to said upper bracket and can move with the upper bracket with the outer circumferential surface of its shaft portion being guided by said guide groove, the steering apparatus comprises a gap setting portion that is in abutment with an upper surface (211 a) of said upper bracket when said guide pin is fixed to said upper bracket to set the length of a gap between a lower surface of said head portion and an upper surface of the upper bracket to a predetermined value; and a spacer (72; 73; 74; 75; 76) made of a synthetic resin that is externally fitted on an outer circumferential surface of the shaft portion of the guide pin and can make collapsing movement or move with its outer circumferential surface being in contact with said guide groove, wherein the outer circumferential surface of said spacer (72; 73; 74; 75; 76) is provided on a cylinder portion (721; 731; 741) or a rectangular cylinder portion (751; 761) provided with two parallel flat portions (755; 765), wherein the cylinder portion (721; 731; 741) or the two flat portions (755; 765) can make collapsing movement or move while being in contact with said guide groove; wherein a flange portion (722; 732; 742; 752; 762) is provided at the top of said spacer (72; 73; 74; 75; 76) and has a diameter larger than the outer circumference of the cylindrical portion (721, 731, 741), or a diameter larger than the rectangular cylinder portion, or has a rectangular shape with sides longer than the sides in contact with said flat plate portion of the rectangular cylinder portion; said head portion of the pin pressing the flange portion (722; 732; 742; 752; 762) of said spacer (72; 73; 74; 75; 76).
