A tilt steering column device, comprising: a steering column that pivotally displaces around a tilt shaft that is provided in a width direction thereof in a front section thereof; a displacement bracket that is fastened to a middle section in an axial direction of the steering column; a steering shaft that is supported on an inner-diameter side of the steering column so as to be able to rotate freely; a support bracket that comprises a top plate section that is supported by a vehicle body, and a pair of support plate sections (15b, 15c) that hang downward from the top plate section, and that are located on both sides in the axial direction of the support bracket; a pair of long holes (17a, 17b) that is provided in portions of the pair of support plate sections (15b, 15c) that are aligned with each other, and that extends in the up-down direction in a partial arc shape that is centered around the tilt shaft; a through hole that is formed in a portion of the displacement bracket that is aligned with the pair of long holes (17a, 17b) so as to penetrate the displacement bracket; a tilt rod member that is inserted through the pair of long holes (17a, 17b) and the through hole in the width direction; an anchor section that is provided at a base-end section of the tilt rod member; a tilt lever that is provided at a tip-end section of the tilt rod member; and a pushing member that increases or reduces a space between the anchor section and the pushing member due to pivotal movement of the tilt lever; and by increasing or reducing the space between the anchor section and the pushing member, a space between inside surfaces of the pair of support plate sections (15b, 15c) is increased or reduced, characterized by a wide section having a width dimension that is equal to or greater than a width dimension in a forward-backward direction of a top-half section of the anchor section or pushing member is provided in a top-end section of at least one long hole of the pair of long holes (17a, 17b), wherein top-half section means the half on the top sides of these members (25, 29) that overlap the wide section when the tilt rod member is positioned at the very top-end section side inside the pair of long holes (17a, 17b). a steering column that pivotally displaces around a tilt shaft that is provided in a width direction thereof in a front section thereof; a displacement bracket that is fastened to a middle section in an axial direction of the steering column; a steering shaft that is supported on an inner-diameter side of the steering column so as to be able to rotate freely; a support bracket that comprises a top plate section that is supported by a vehicle body, and a pair of support plate sections (15b, 15c) that hang downward from the top plate section, and that are located on both sides in the axial direction of the support bracket; a pair of long holes (17a, 17b) that is provided in portions of the pair of support plate sections (15b, 15c) that are aligned with each other, and that extends in the up-down direction in a partial arc shape that is centered around the tilt shaft; a through hole that is formed in a portion of the displacement bracket that is aligned with the pair of long holes (17a, 17b) so as to penetrate the displacement bracket; a tilt rod member that is inserted through the pair of long holes (17a, 17b) and the through hole in the width direction; an anchor section that is provided at a base-end section of the tilt rod member; a tilt lever that is provided at a tip-end section of the tilt rod member; and a pushing member that increases or reduces a space between the anchor section and the pushing member due to pivotal movement of the tilt lever; and by increasing or reducing the space between the anchor section and the pushing member, a space between inside surfaces of the pair of support plate sections (15b, 15c) is increased or reduced, characterized by a wide section having a width dimension that is equal to or greater than a width dimension in a forward-backward direction of a top-half section of the anchor section or pushing member is provided in a top-end section of at least one long hole of the pair of long holes (17a, 17b), wherein top-half section means the half on the top sides of these members (25, 29) that overlap the wide section when the tilt rod member is positioned at the very top-end section side inside the pair of long holes (17a, 17b).
