- the first restriction urging member 59 is configured such that the operation restriction engagement portion 57 is notched to the main operation member 50 from the first unlocked position (the position in FIG. 6) where the operation restriction engagement portion 57 is separated from the main operation member 50.
- the first restriction release operation member 56 is biased toward a first lock position (position in FIG. 5) that engages with the portion 51 and restricts the operation of the main operation member 50. That is, when no operating force is applied to the first restriction release operation member 56 and the main operation member 50, the first restriction release operation member 56 is urged from the first unlock position by the first restriction urging member 59. And returned to the first lock position.
- the first restriction release operation member 56 when the first restriction release operation member 56 is disposed at the first unlocked position and the operation of the main operation member 50 is started, the hand is released from the first restriction release operation member 56. In addition, the first restriction release operation member 56 comes into contact with the outer peripheral surface of the rotating portion 50b of the main operation member 50 in operation, and the return to the first lock position is prevented. On the other hand, when the operation of the main operation member 50 is finished and the release member 41 returns to the restriction position by the urging force from the main urging member 49, the first urging force from the first restriction urging member 59 causes the first The restriction release operation member 56 automatically returns to the first lock position.
- the guardian who wants to fold the stroller 10 moves the first restriction releasing operation member 56 against the first restriction biasing member 59 until the operation of the operation member 50 is started. Move it to the locked position. In the unfolded state of the stroller 10, the first restriction release operating member 56 automatically returns to the first lock position, and an unintended folding operation of the stroller 10 (stroller body 11) can be effectively prevented. .
- the contact surface 57a of the operation restriction engagement portion 57 that comes into contact with the notch 51 and restricts the operation of the main operation member 50 is the first contact position 57a.
