Abstract
Provided are a pretensioner, a retractor, and a seat belt device in which strength and slidability of a rod-shaped power transmission member may both be achieved. A pretensioner includes a ring gear on which the spool is rotatably disposed, and power transmission units for transmitting power to the ring gear in an emergency. The power transmission units includes a rod-shaped power transmission member for transmitting power to the ring gear while being plastically deformed, a tip reinforcing member disposed on a tip side of the power transmission member, a pipe for containing the power transmission member, and a gas generator disposed at an end of the pipe. The tip reinforcing member has higher strength than the power transmission member.
