(First embodiment)
1 and 2 show an example of a blind to which the present invention can be applied. In FIG. 1, the blind includes a head box 10 as a support member. The head box 10 is fixed to a fixed surface such as a wall surface or a window frame by a plurality of brackets 12 and extends in the left-right direction as a longitudinal direction. The cross-sectional shape of the head box 10 is a U-shape with an upper opening as shown in FIG. In the specification and claims, the left-right direction is a direction that coincides with the longitudinal direction of the head box 10, the up-down direction is orthogonal to the left-right direction, and the solar radiation shielding material is supported from the head box 10. (Normally, but not limited to the vertical direction), the front-rear direction is a direction orthogonal to both the left-right direction and the up-down direction.

  A rotating shaft 14 is disposed in the head box 10 along the longitudinal direction thereof. The rotary shaft 14 is rotatable about its axis, and an elevating rotary drum 16 that can rotate integrally with the rotary shaft 14 is provided on the rotary shaft 14 at an appropriate interval. One end of a lifting / lowering cord 18 and / or a ladder cord 20 is connected to each lifting / lowering rotary drum 16, and the other end or the other end of the cords 18, 20 is suspended from the head box 10 and is a slat that is a solar radiation shielding material. The ladder cord 20 suspends and supports the slat 24 in a suspended or aligned manner, and moves the slat 24 up and down and opens and closes it.

  The rotating shaft 14 is rotationally driven by a motor device 26. The motor device 26 is a rotatable motor that is operatively connected to a non-rotating motor outer shape portion 26a that constitutes the outermost side and a rotor provided inside the motor outer shape portion 26a and protrudes from both ends of the motor outer shape portion 26a. An output shaft 26b, and the motor output shaft 26b is connected to the rotary shaft 14. The motor device 26 can rotate the rotation shaft 14 by the control of the control unit 28 that receives the operation command. The motor device 26 rotates the rotation shaft 14 in an arbitrary rotation direction, so that the solar radiation shielding material 24 is driven. Can be opened and closed.

  In fixing the motor device 26 in the head box 10, in the present invention, one or a plurality of motor mounts 30 that are not required to be screwed are used. The motor mount 30 is a molded product made of a material having a vibration absorbing property made of a soft elastic material, and the inner shape of the motor mount 30 can surround at least a part of the motor outer portion 26a. It corresponds to a part of the outer shape of 26a.

  In the example shown in FIGS. 3 to 5, the motor outer portion 26 a is symmetrical, and both left and right end portions have a rectangular tube shape, and the motor mount 30 has both left and right end portions of the motor outer portion 26 a. A pair of opposing motor mounts 30 having the same shape are used so that they can be enclosed. The inner shape of each motor mount 30 covers the front and rear, top and bottom, right and left surfaces of the left and right end portions of the motor outer portion 26a, and a part of the motor outer portion 26a is formed by the pair of motor mounts 30. The front and back, the top and bottom, and the surface facing left and right can be covered.

  Each motor mount 30 is formed with a through hole 30a extending in the left-right direction. The motor output shaft 26b passes through the through hole 30a in a loosely fitted state.

  Further, at least a part of the outer shape of each motor mount 30 matches at least a part of the inner shape of the head box 10, and at least a part of the front and rear and lower outer wall surfaces of each motor mount 30 is formed. The head box 10 is in close contact with at least a part of the front and rear and lower inner wall surfaces.

  Further, at the lower part of each motor mount 30, there are engaging projections 30 b as first engaging portions that engage with a plurality of locking holes 10 b as first engaged portions formed on the lower surface of the head box 10. A second engagement that is formed on the front and rear portions of each motor mount 30 and that engages with a plurality of engagement ribs 10c as second engaged portions that are formed on the front and rear inner wall surfaces of the head box 10 and extend in the left-right direction. An engaging recess 30c as a portion is formed.

  The procedure for fixing the motor device 26 using the above motor mount 30 will be described. The motor output shaft 26b is passed through the through hole 30a of the motor mount 30 from the state shown in FIG. The left and right ends are surrounded by the motor mounts 30, and the motor device 26 and the motor mount 30 are integrally inserted from the upper opening of the head box 10 as shown in FIG. 7. Although the upper flange of the head box 10 and the engaging rib 10c interfere with the motor mount 30 during insertion, the motor mount 30 and the head box 10 are elastically deformed to pass through the motor mount 30 and engage protrusion 30b is engaged with the engagement hole 10b of the head box 10, and the engagement recessed part 30c of the motor mount 30 is engaged with the engagement rib 10c.

  Due to the engagement between the engagement protrusion 30b and the engagement hole 10b, the motor mount 30 and the motor device 26 are positioned and fixed with respect to the head box 10 in the left-right and front-rear directions, and the engagement recess 30c and the engagement rib 10c.

In addition, the front and rear and lower outer wall surfaces of the motor mount 30 are in close contact with the front and rear and lower inner wall surfaces of the head box 10, so that the motor mount 30 is fixed to the head box 10 so as not to rotate and roll.

  Since vibration generated during the operation of the motor device 26 is absorbed by the motor mount 30, it can be prevented from being transmitted to the head box 10.

  When the motor device 26 is assembled, screwing is not required at all, so that the assemblability and workability are good and the generation of noise due to loosening of the screws can be prevented. In particular, since the motor mount 30 is in close contact with the head box 10 and absorbs vibrations of the head box 10 itself, the motor mount 30 and the head box 10 do not resonate and noise can be prevented.

  Further, since the outer wall surface of the motor mount 30 is in close contact with the inner wall surface of the head box 10 and is fixed to the head box 10 so as not to rotate and roll, the reaction force of the motor rotation is reduced when the motor device 26 is operated. It can be received and effectively absorbed by the motor mount 30.

  In this embodiment, the motor mounts 30 are attached to the left and right ends of the motor device 26. However, the present invention is not limited to this. The motor mounts 30 are attached to only the left and right ends of the motor device 26, and are cantilevered. May be fixed.
