• a mount bracket including a fixation portion having a plate shape and to be fixed to a vehicle body, and a suspended portion hanging from the fixation portion;
• a jacket guide disposed between the jacket and the mount bracket and configured to guide the jacket;
• and
• a clamp bolt having a shaft penetrating the jacket, the mount bracket, and the jacket guide,
• wherein the suspended portion includes
• a first wall hanging from the fixation portion, being adjacent to the jacket guide, and extending along the jacket guide,
• a second wall hanging from the fixation portion on an opposite side from the jacket across the first wall and extending along the first wall, and
• a connecting portion hanging from the fixation portion and connecting at least any set of front ends and rear ends of the first wall and the second wall to each other,
• the fixation portion includes a surrounded portion surrounded by the first wall, the second wall, and the connecting portion, and
• operation of an operating lever protruding from the suspended portion actuates the clamp bolt to switch between a pressure contact state where the jacket and the mount bracket are in pressure contact with each other and a non-pressure contact state where the jacket and the mount bracket are not in pressure contact with each other.
