At a shift lever device, a shift lever is supported at a retainer due to the shift lever being inserted into the retainer from an upper side portion, and select shafts of the shift lever being inserted into select frames of the retainer. Here, at the select shafts, amounts of projection of circular shafts and intermediate shafts are small as compared with amounts of projection of plate shafts. At a time when the select shafts are inserted into the select frames, the circular shafts and intermediate shafts can pass supporting pillars of the select frames, and an angle of tilting of the shift lever with respect to the retainer in a left-right direction can be made to be small. Therefore, a left-right direction dimension of the retainer can be made to be small, and the shift lever device can be made to be compact in the left-right direction.
