The first lock member 62 is held in this unlocked state by urging the end face 62e by the panel 63a via the ball 63b. As a result, it is possible to save work for the mounting operator to hold the first lock member 62 in the non-locked state, and to improve work efficiency. Incidentally, by swinging the first lock member 62 to the position C in FIG. 4, it is possible to fix the first lock member 62 so that it does not protrude toward the operator side, and to perform the mounting operation.

- the structure is such that the control 30 having the mounting hole 32c can be attached to the mounting part 32b formed protruding from the mounting surface 32a, the conventional shape of the control is used as it is. Can be used. Therefore, it is not necessary to create a new shape of control wheel.
- the first locking member 62 biases the side surface 62d by tilting the first locking member 62 toward the insertion opening 42c and changing the biasing surface by the ball 63b from the end surface 62e to the side surface 62d. And swings so as to shift to the locked state.
- the lock pin 71 comes into contact with the engaging portion 42e and is biased and displaced in a direction opposite to the biasing direction by the panel 72 to shift to the locked state. As a result, it is displaced and held at a position where it engages with the engaging portion 42e.
- the restrictor cotter 50 is restricted from moving toward the upper edge of the insertion opening 42c by the contact between the flange 52a and the tip 62c, so that it comes out of the mounting hole 32c. There is no habit of falling. As a result, the restraint 30 can be securely fixed to the restraint head 40.
- the swing of the first lock member 62 when the locked state force is shifted to the unlocked state is restricted by the engagement between the locking claw 71a of the lock pin 71 and the engaging portion 42e. Therefore, even when a force is applied in the direction in which the first locking member 62 is rocked in an unlocked state from the outside (in the direction of arrow b in FIG. 4), the locked state can be reliably maintained even when the vehicle is Vibration when driving It can suppress that a locked state is cancelled
- the first lock member 62 is swung so that the locked state force is also in the unlocked state. Since it is necessary to counteract the urging force by the panel 63a, it is possible to suppress the release of the locked state due to vibration during driving of the vehicle.
