By adopting a shape that allows passage through the pipe 20, the first and second end members 54 and 55 can pass through the lever pipe 20. Further, since the first and second end members 54 and 55 are provided with sliding portions 54a and 55a that can slide on the inner peripheral surface of the lever pipe 20, the first and second end members 54 and 55 are provided. Can be applied to the inner circumferential surface of the lever pipe 20 at different positions in the axial direction of the lever pipe 20. Therefore, compared to the conventional case, the pin-side end member 53 is less inclined in the lever pipe 20 and the detent pin 40 is less inclined.
Therefore, even when the detent pin 40 is unilaterally engaged with the shift lock plate 90, it is possible to prevent the detent pin 40 from inclining against the shift lock plate 90, and the operational feeling is improved, and the detent pin 40 is improved. It is possible to prevent the deviation from 90.

Even when the bent portion 22 is provided in at least a part of the lever pipe 20, the pin side end member 53 has a two-part configuration, so that the pin side end member 53 can pass through the lever pipe 20.
The first and second end members 54 and 55 have small diameter portions 54b and 55b having a shape smaller than the outermost shape of the sliding portion, and at least a part of the small diameter portion 54b of the first end member 54 is the first. Since it is located between the sliding portion 54a of the end member 54 and the sliding portion 55a of the second end member 55, the distance (span) between the two sliding portions 54a and 55a can be increased. As a result, the end member 53 is less inclined in the lever pipe 20 than when the distance between the two sliding portions 54a and 55a is short.
