An assembly method for a steering column support apparatus, the steering column support apparatus comprising: a bracket on the vehicle side that has a locking hole that is provided in the center section in the width direction and that extends in the axial direction of the steering column, and that is supported by and fastened to the vehicle body and does not displace in the forward direction during a secondary collision; a bracket on the column side that is supported by the steering column and that displaces in the forward direction together with the steering column during a secondary collision; and a locking capsule (47, 47a-e) that is locked in the locking hole in the both ends thereof with fastened to the bracket on the column side, and of which both sides on the top end are located on the top side of the bracket on the vehicle side in the portions on both sides of the locking hole, with part of the locking capsule (47, 47a-e) located inside the locking hole, this locking capsule (47, 47a-e) and the bracket on the vehicle side being connected together by a connecting member (50, 50a) that shears due to an impact load that is applied during the secondary collision, and the bracket on the column side being supported by the bracket on the vehicle side so that the bracket on the column side can break away in the forward direction due to an impact load that is applied during a secondary collision; this assembly method comprising steps of: fitting the locking capsule (47, 47a-e) into the locking hole; with the positional relationship between the locking capsule (47, 47a-e) and bracket on the vehicle side in a state shifted from the final assembled state, aligning together part of a plurality of through holes (49a-b) on the capsule side that are formed in part of the locking capsule (47, 47a-e) such that they pass in the vertical direction through the portions that overlap in the vertical direction the portion of the bracket on the vehicle side that surrounds the locking hole, and part of a plurality of receiving sections (54, 55a-b) on the bracket side that are formed in the portion of the bracket on the vehicle side that surrounds the locking hole; inserting pin shaped members such that the pin shaped members span between part of these through holes (49a-b) on the capsule side and part of the receiving sections (54, 55a-b) on the bracket side; positioning the locking capsule (47, 47a-e) and bracket on the vehicle side in the final assembled state, causing the pin shaped members to shear; aligning the remaining through holes on the capsule side with the remaining receiving sections (54, 55b) on the bracket side; and inserting connecting members (50, 50a) such that the connecting members span between these remaining through holes on the capsule side and the remaining receiving sections (54, 55b) on the bracket side. a bracket on the vehicle side that has a locking hole that is provided in the center section in the width direction and that extends in the axial direction of the steering column, and that is supported by and fastened to the vehicle body and does not displace in the forward direction during a secondary collision; a bracket on the column side that is supported by the steering column and that displaces in the forward direction together with the steering column during a secondary collision; and a locking capsule (47, 47a-e) that is locked in the locking hole in the both ends thereof with fastened to the bracket on the column side, and of which both sides on the top end are located on the top side of the bracket on the vehicle side in the portions on both sides of the locking hole, with part of the locking capsule (47, 47a-e) located inside the locking hole, this locking capsule (47, 47a-e) and the bracket on the vehicle side being connected together by a connecting member (50, 50a) that shears due to an impact load that is applied during the secondary collision, and the bracket on the column side being supported by the bracket on the vehicle side so that the bracket on the column side can break away in the forward direction due to an impact load that is applied during a secondary collision; fitting the locking capsule (47, 47a-e) into the locking hole; with the positional relationship between the locking capsule (47, 47a-e) and bracket on the vehicle side in a state shifted from the final assembled state, aligning together part of a plurality of through holes (49a-b) on the capsule side that are formed in part of the locking capsule (47, 47a-e) such that they pass in the vertical direction through the portions that overlap in the vertical direction the portion of the bracket on the vehicle side that surrounds the locking hole, and part of a plurality of receiving sections (54, 55a-b) on the bracket side that are formed in the portion of the bracket on the vehicle side that surrounds the locking hole; inserting pin shaped members such that the pin shaped members span between part of these through holes (49a-b) on the capsule side and part of the receiving sections (54, 55a-b) on the bracket side; positioning the locking capsule (47, 47a-e) and bracket on the vehicle side in the final assembled state, causing the pin shaped members to shear; aligning the remaining through holes on the capsule side with the remaining receiving sections (54, 55b) on the bracket side; and inserting connecting members (50, 50a) such that the connecting members span between these remaining through holes on the capsule side and the remaining receiving sections (54, 55b) on the bracket side.
