Since the vector is set so that the joint portion escapes in the circumferential direction, the mechanical engagement of the first engaged portion with respect to the first engagement portion and the mechanical engagement of the first engagement portion with respect to the first arm portion are performed. Biting is less likely to occur.
- the first engaging portion quickly disengages from the first engaged portion.
- the angle formed by the contact plane of the second engaged portion with respect to the second engaging portion with respect to the plane contacting the outer peripheral surface of the second cylindrical portion in the second engaged portion is set to an acute angle, that is, the second engaged portion.
- Vector setting so that when the second cylindrical part rotates in the direction in which the joint part is pressed against the second engaging part, the second engaging part escapes in the circumferential direction using the rotational force from the second cylindrical part Therefore, mechanical biting of the second engaged portion with respect to the second engaging portion and mechanical biting of the second engaging portion with respect to the second arm portion are less likely to occur. As a result, the second engaging portion is quickly detached from the second engaged portion.

Since the second resistance applying mechanism for suppressing the relative rotation of the second clutch drum with the second input shaft is provided between the second input shaft and the second clutch drum, The clutch drum follows the rotation of the first input shaft by the first resistance applying mechanism, and the second clutch drum follows the rotation of the second input shaft by the second resistance applying mechanism during the initial torque of the second input shaft. As a result, the first engaging portion attached to the first clutch drum does not unintentionally engage with the first engaged portion of the first output drum, and the first engaging portion attached to the second clutch drum is not intended. Since the two engaging portions do not unintentionally engage with the second engaged portion of the second output drum, the first and second shielding members are reliably raised and lowered independently by operating one operation cord. Can be made.
- the first engagement portion is provided with a first return spring mechanism that biases the first engagement portion so as to be pulled inward in the radial direction of the first input shaft. Since the second return spring mechanism that urges the joint portion to be pulled inward in the radial direction of the second input shaft is provided in the second engaging portion, the first output shaft pushes the first shielding member by the weight of the first shielding member. Even if the first output drum rotates due to the rotation of the first output shaft, the first return spring mechanism retracts the first engagement portion radially inward of the first input shaft. Therefore, the rotational force of the first output shaft is not transmitted to the first input shaft.
- the second return spring mechanism is second. Since the engaging portion is kept in a state of being retracted radially inward of the second input shaft, the rotational force of the second output shaft is not transmitted to the second input shaft. As a result, the independence of the raising and lowering of the first and second shielding members can be reliably maintained.
