Abstract: A driving-side concave-convex portion of a driving-side transmission member is engaged with an elastic member. The driving-side concave-convex portion is engaged with an intermediate concave-convex portion of an intermediate transmission member with a circumferential gap being interposed therebetween. A driven-side concave-convex portion of a driven-side transmission member is engaged with the elastic member. The driven-side concave-convex portion is engaged with the intermediate concave-convex portion with a circumferential gap being interposed therebetween. Both axial side surfaces and a periphery of the intermediate transmission member are covered by a side surface covering portion and a periphery covering portion of the elastic member.

Abstract: Circumferential rigidity of both axial end portions of each coupling-side convex portion is lower than circumferential rigidity of an axially intermediate portion of each coupling-side convex portion. The drive-side concave-convex portion is engaged with a half portion on the other axial side of the coupling-side concave-convex portion. The driven-side concave-convex portion is engaged with a half portion on one axial side of the coupling-side concave-convex portion.

Abstract: Reinforcing ribs (33a and 33b) are provided between mounting plate parts (30a and 31b) and support plate parts (31a and 31b) forming a support bracket (18a). Side plate parts (40a and 40b) forming a distance bracket (17a) are disposed between the support plate parts (31a and 31b), and an outer column (13a). When an adjustment lever (26a) is operated to hold a steering wheel at a position after adjustment, a steering column (6a) is pushed toward an upper side by column pressing parts (42a and 42b) provided at the side plate parts (40a and 40b), and, therefore, a pair of widened parts (43a and 43b) provided at upper parts of the side plate parts (40a and 40b) are pushed and expanded to the outside in a width direction. The widened parts (43a and 43b) are sandwiched between the support plate parts (31a and 31b) and the outer column (13a).
