The shaft portion 18 of the contact member 17 is formed with the slit 19 which opens upward and extends in the axial direction, so that the outer diameter of the shaft portion 18 can be elastically reduced. Thereby, as shown in the exploded perspective view seen from the back surface side of FIG. 13 (a) and the perspective view seen from the back surface side of FIG. 13 (b), the cross section approximately C shape formed in the back surface side of wiring cover 5 The shaft portion 18 can be easily inserted into the shaft groove 5C of
The contact member 17 has a portion projecting radially outward from the shaft portion 18 across the notch 5D (FIG. 13A), and the lower surface is a contact that receives the actuating pin 16 of the stroke type damper It becomes the surface 20 (FIG. 13 (a) and FIG. 14).

The wiring covers 5 and 5 are pivoted between a fully closed state in which the gap between the top plates 1 and 1 is closed horizontally and a fully open state in which the wiring covers 5 and 6 are vertically made as shown in the enlarged partial sectional view of FIG. .
When the wiring cover 5 is turned from the fully open state to the closing direction of the wiring cover 5 as shown in the enlarged partial sectional view of FIG. 15, the actuating surface 16 of the stroke type damper is applied to the contact surface 20 of the contact member 17 of the wiring cover 5 Will abut.
From the state of FIG. 15 to the state of FIG. 14, while the semispherical upper end of the actuation pin 16 of the stroke type damper is in sliding contact with the arc-shaped abutting surface 20 convex below the wiring cover 5, It cancels a part of the rotational moment due to its own weight, and is set to close slowly even if the hand is removed from the wiring cover 5.

In the above-described configuration of the wiring cover 5 and the wiring cover support 9A provided with the stroke type damper, the contact member 17 with which the operation pin 16 of the stroke type damper abuts is a separate member from the wiring cover 5 (for example, 13).
The abutting member 17 may be integrally provided on the wiring cover 5 so as to provide an abutting surface which is a downwardly convex arc surface instead of forming a separate member from the wiring cover 5.
However, providing the contact member as a separate member as in the present embodiment is advantageous in that the material of the wiring cover to be extrusion molded can be suppressed.

<Operation and effect of a configuration provided with a stroke type damper>
As shown in FIGS. 14 and 15, in the configuration in which the wiring covers 5, 5,... Are provided rotatably at the duct opening of the work bench B1, which is furniture, the shaft support of the wiring cover support 9A. The base ends of the wiring cover 5 are supported by the support shafts 13 and 13, and the wiring cover 5 is supported so as to be vertically rotatable.
Then, the stroke-type damper is vertically supported at a position near the support shafts 13 and 13 of the wiring cover support 9A, and the operation pin 16 of the stroke-type damper provided with a hemispherical contact portion at the upper end is disposed upward. The operation pin 16 abuts on the contact surface 20 of the contact member 17 of the wiring cover 5 until the wiring cover 5 reaches a horizontal state from the inclined state at a predetermined angle, and the wiring cover 5 is elastically urged in the direction of opening. doing.

  Therefore, since the stroke type damper is provided at a position close to the pivot portion, the damper function can be used from the early stage of the operation of closing the wiring cover 5, and the difference in weight of the wiring cover 5 can be absorbed. Further, the contact noise between the operation pin 16 of the stroke type damper and the contact member 17 of the wiring cover 5 can be reduced by contacting before the acceleration is applied. Although the cost can be reduced by using the stroke type damper which is cheaper than the rotary damper, the quietness at the time of closing the wiring cover 5 comparable to the rotary damper can be obtained. Furthermore, when the wiring cover 5 is lifted and opened from the closed state, it can be lightly opened with the aid of the elastic biasing force of the stroke type damper. Furthermore, since it becomes difficult to apply a load to the operation pin 16 of a stroke type damper from a diagonal direction, a stroke type damper can be arrange | positioned in the position near a bearing part. By sliding off the diagonal load originally applied to the damper body, the following effects are possible.

  Moreover, since the contact surface 20 of the contact member 17 of the wiring cover 5 with which the actuating pin 16 of the stroke type damper abuts is a downwardly convex circular arc surface, the load on the actuating pin 16 of the stroke type damper from an oblique direction Furthermore, the stroke type damper can be disposed at a position closer to the bearing portion. In particular, the upper end portion of the operating pin 16 is a hemispherical contact portion, and the contact surface 20 of the contact member 17 of the wiring cover 5 with which the operation pin 16 of the stroke type damper contacts is an arc surface convex downward. Thus, the sliding resistance between the operating pin 16 and the contact surface 20 can be significantly reduced. In addition, the durability of the stroke type damper can be improved.

  Furthermore, when the wiring cover 5 is completely closed, it becomes horizontal, and when the contact portion of the operation pin 16 passes through the arc surface of the contact surface 20 and is in contact with the horizontal surface, the wiring cover 5 is closed. When in the horizontal position, only the axial force acts on the actuating pin 16, and no excessive force is applied to the stroke type damper even if the posture is maintained for a long time.

  Furthermore, the main body of the wiring cover 5 is made of an extruded material of aluminum, and the portion of the wiring cover support 9A other than the stroke type damper and the wiring cover support 9B are molded articles of synthetic resin, the wiring cover support 9A, It has a structure in which slitted support shafts 13 and 13 formed so that the axial direction is horizontally oriented are closely fitted rotatably in 9B. As a result, even if the wiring cover 5 is long, since the rigidity is high, it is possible to prevent the bending and to realize the rotation operation in which the bearing portion does not rattle. Furthermore, when the support shafts 13 and 13 of the wiring cover support 9A and 9B are fitted into the shaft groove 5C of the wiring cover 5, the outer diameters of the support shafts 13 and 13 are elastically reduced due to the presence of the slits. This makes it possible to maintain a close fit because the support shaft tries to restore its original shape after fitting.

  Furthermore, as shown in FIG. 10, the support shafts 13 and 13 of the wiring cover support 9A are provided with both ends protruding laterally to the support base 12 protruding upward, and the support shafts 13 and 13 The contact member 17 is inserted between them as shown in FIG. 13 (b). Then, the contact member 17 has a portion projecting radially outward from the shaft portion 18 across the notch 5D (FIG. 13A). Thereby, the lateral displacement (movement in the lateral direction) of the wiring cover 5 can be restricted.
