Vehicular holding device

A vehicular holding device, which is configured to hold a vehicle component, wherein the vehicular holding device is configured to enable a state of the vehicular holding device to be switched between an ON state and an OFF state,

• the ON state is a state in which the vehicle component is held in a state where a displacement of the vehicle component in an axial direction of the vehicle component is prevented,
• the OFF state is a state in which the vehicle component is held in a state where the displacement of the vehicle component in the axial direction is possible,
• the vehicular holding device comprises:
• at least one engagement portion configured to be displaced in a direction perpendicular to the axial direction in such a manner as to be brought into contact with or disengaged from the vehicle component, be located in the ON state at a position where the at least one engagement portion is engaged with an engaged portion of the vehicle component, and be located in the OFF state at a position where the at least one engagement portion is disengaged from the engaged portion, wherein the at least one engagement portion has a first end and an axially opposed second end;
• a cam mechanism configured to displace the at least one engagement portion from the position in the OFF state to the position in the ON state;
• and
• an axial restraining portion configured to receive, by facing and coming into contact with the first end of the at least one engagement portion in the axial direction, a force in the axial direction acting on the at least one engagement portion from the second end of the at least one engagement portion and toward the first end of the at least one engagement portion,
• wherein the at least one engagement portion comprises a plurality of engagement portions provided in such a manner as to surround an outer circumference of the vehicle component, and
• wherein the vehicular holding device comprises an annular spring partially opened and configured to apply, to the plurality of engagement portions, an elastic force for displacing the plurality of engagement portions from the positions in the ON state to the positions in the OFF state.
