摘要： [Object] To provide a retractor that is manufacturable at a much lower cost by making a pretensioner operate more effectively, by minimizing the length of a pipe so that a weight reduction is realized effectively, and by easing the restriction for the shape of a guide member.
[Solution] A pipe 17 in which a plurality of balls as force transmitting members are provided includes an attaching portion 17c as a projection provided at one end portion 17a thereof. A guide member 18 having a guide surface 18c that guides the balls has attaching grooves 18 as recesses. The attaching portion 17c is fitted into the attaching grooves 18, whereby the pipe 17 is attached around the outer circumference thereof to the guide member 18 attached to a frame. Since the guide member 18 is provided on the outer circumference of the pipe 17, the pipe 17 can be shortened.
