Abstract: Provided is a structure capable of accommodating differences in length and diameter of a winding cone. This cam unit is provided with: a cone cap which is removably fitted to a winding cone for winding and unwinding a lifting cord and which rotates together with the winding cone; a rotating drum which is engaged with the cone cap so that the axial movement of the winding drum is limited, the rotating drum being configured so that, within a predetermined angular range, the rotating drum is capable of rotating relative to the cone cap, and so that, outside the predetermined angular range, the rotating drum rotates together with the cone cap; and a cam clutch which rotates together with the cone cap and which is engaged with the rotating drum so that the cam clutch moves in the axial direction relative to the cone cap as the rotating drum rotates.

Abstract: Provided is an endless operation cord that is easy to replace. The present invention provides an operation cord including: a main cord having one and the other ends; a first coupling part disposed at the one end; and a second coupling part disposed at the other end. The first and second coupling parts can be coupled together directly or via a coupling member and can be coupled or uncoupled by means of a relative rotation between the adjacent coupling parts or between the adjacent coupling parts and coupling member or a relative movement in a direction other than a length direction of the main cord between the adjacent coupling parts or between the adjacent coupling parts and coupling member.

Abstract: [Problem] To provide a shielding device provided with a speed adjustment unit which is capable of automatically adjusting the movement speed of a shielding material using a simple configuration, and with which noise during operation is suppressed. [Solution] According to the present invention, provided is a shielding device in which a shielding material is opened and closed by rotating a winding shaft. The shielding device is provided with a speed adjustment unit for automatically adjusting the movement speed of the shielding material. The speed adjustment unit is provided with: a housing for accommodating a viscous fluid; and a moving member which is accommodated inside the housing, and which moves in accordance with the rotation of the winding shaft. Furthermore, the speed adjustment unit is configured such that the resistance force that the moving member receives from the viscous fluid changes in accordance with the movement of the moving member.
