A webbing take-up device is obtained capable of restricting movement of a clutch member in the axial direction of a second gear. In the webbing take-up device, a movement prevention portion is formed, on a rotor side, at an intermediate bottom portion of a large gear portion, and a clutch spring attached to the rotor abuts the movement prevention portion, thereby preventing any movement of the clutch spring further to the intermediate bottom portion side. Movement of the clutch spring in the axial direction of the rotor can accordingly be suppressed, enabling movement of the clutch spring in the axial direction of the rotor to be restricted.

Webbing take-up device

A webbing take-up device is obtained capable of suppressing slight axial direction movement of a gear configuring a mechanism to release overload. A large gear portion of a two-step gear configuring an overload release mechanism of the webbing take-up device is sandwiched between a small gear portion end face of a small gear portion and a bottom portion of a rotor. This thereby enables rattling which is slight axial direction movement of the large gear portion to be suppressed.

In a webbing take-up device, a housing portion configuring a recessed shape opening in a direction orthogonal to a fastening direction of a screw is formed to a body. A head portion of the screw is housed inside the housing portion, and the screw is inserted through an insertion portion in one side wall of the housing portion and fastened to the frame. A tool hole is formed in another side wall of the housing portion. A tool can accordingly be inserted through the tool hole to fasten the screw to the frame. The other side wall is formed with a fixing hole that fixes a spring cover, the fixing hole overlapping with the head portion as viewed along the screw fastening direction. A placement space of the screw and the fixing hole in the body as viewed along the screw fastening direction can accordingly be made small.
