A steering column support apparatus, comprising: a front support bracket that is fastened to a vehicle body and that has a pair of support plate sections that are parallel with each other and separated in a width direction of the vehicle body; a tilt pivot shaft that is arranged in the width direction of the vehicle body so as to be spanned between the side plate sections; a pivot bracket that is provided on part of a housing of an electric assist apparatus, and that has a through hole through which the tilt pivot shaft is inserted and supports a steering column, which supports a steering shaft so as to be able to freely rotate, by way of the housing; and a pair of bushings (30g-30i), that are made of an elastic material or a low friction material so as to be formed into an annular shape as a whole, and that are fitted around both end sections of the tilt pivot shaft in an axial direction of the tilt pivot shaft, each of the pair of bushings (30g-31i) having a cylindrical section that is held between an outer circumferential surface of the tilt pivot shaft and an inner circumferential surface of the through hole; and a circular ring-shaped side plate section (32g-32i) that extends outward in a radial direction of the pair of bushings (30g-30i) from one end section of the cylindrical section of each of the pair of bushings (30g-30i) in the axial direction of the pair of bushings (30g-30i), and is held between a side surface of the pivot bracket and an inside surface of each of the pair of support plate section; characterized in that a concave section (38, 38a-38c, 39) is provided in the middle section in the radial direction of the at least one of both side surfaces of the side plate section (32g-32i) of each of the pair of bushings (30g-30i), so as not to come in contact with opposing surfaces that face the at least one of both side surfaces of the side plate sections (32g-32i) of each of the pair of bushings (30g-30i) in a neutral state where at least an assist force that is applied to the steering shaft from the electric assist apparatus is not generated, the concave section (38, 38a-38c, 39) allowing a radially outside end section of the side plate section (32g-32i) of each of the pair of bushings (30g-30i) to easily bend, wherein circular ring shaped concave grooves that are continuous around the entire circumference are formed in the middle section in the radial direction of the outside surfaces so as to be concentric with the side plate sections. a front support bracket that is fastened to a vehicle body and that has a pair of support plate sections that are parallel with each other and separated in a width direction of the vehicle body; a tilt pivot shaft that is arranged in the width direction of the vehicle body so as to be spanned between the side plate sections; a pivot bracket that is provided on part of a housing of an electric assist apparatus, and that has a through hole through which the tilt pivot shaft is inserted and supports a steering column, which supports a steering shaft so as to be able to freely rotate, by way of the housing; and a pair of bushings (30g-30i), that are made of an elastic material or a low friction material so as to be formed into an annular shape as a whole, and that are fitted around both end sections of the tilt pivot shaft in an axial direction of the tilt pivot shaft, each of the pair of bushings (30g-31i) having a cylindrical section that is held between an outer circumferential surface of the tilt pivot shaft and an inner circumferential surface of the through hole; and a circular ring-shaped side plate section (32g-32i) that extends outward in a radial direction of the pair of bushings (30g-30i) from one end section of the cylindrical section of each of the pair of bushings (30g-30i) in the axial direction of the pair of bushings (30g-30i), and is held between a side surface of the pivot bracket and an inside surface of each of the pair of support plate section; characterized in that a concave section (38, 38a-38c, 39) is provided in the middle section in the radial direction of the at least one of both side surfaces of the side plate section (32g-32i) of each of the pair of bushings (30g-30i), so as not to come in contact with opposing surfaces that face the at least one of both side surfaces of the side plate sections (32g-32i) of each of the pair of bushings (30g-30i) in a neutral state where at least an assist force that is applied to the steering shaft from the electric assist apparatus is not generated, the concave section (38, 38a-38c, 39) allowing a radially outside end section of the side plate section (32g-32i) of each of the pair of bushings (30g-30i) to easily bend, wherein circular ring shaped concave grooves that are continuous around the entire circumference are formed in the middle section in the radial direction of the outside surfaces so as to be concentric with the side plate sections.
