The member 10 can be fixed relative to the end post 20A.

Moreover, since the projecting portion 16 is provided at the second end portion 14 of the horizontal beam fixing member 10, the second end portion 14 of the horizontal beam fixing member 10 having the projecting portion 16 inserted into the concave portion 22 of the end strut 20A is the end. It is possible to suppress a large protrusion from the front surface of the strut 20A (the surface facing outward in the longitudinal direction of the horizontal beam 25). In addition, since the end portion 26 of the horizontal rail 25 can be held by inserting it into the insertion recess 12 of the horizontal rail fixing member 10, compared to the case where the horizontal rail 25 is provided with a receiving groove extending in the longitudinal direction. , relative alignment between the horizontal beam fixing member 10 and the horizontal beam 25 can be easily performed, and workability can be improved. Further, since the horizontal beam fixing member 10 has a bottomed cylindrical shape with the second end portion 14 on the bottom side, a cover that covers the upper side of the receiving groove extending in the longitudinal direction of the horizontal beam 25 and the outer side of the horizontal beam 25 in the longitudinal direction are provided. The structure can be simplified compared to the one that requires a covering cap.

Further, in this embodiment, a cap member 19 is provided to cover the opening of the stopper insertion hole 17 on the second side surface 18 side. Therefore, the head of the fastener 8 and the fastener insertion hole 17 can be covered with the cap member 19, and the appearance can be improved.

Further, in this embodiment, the projecting portion 16 is configured to be rotatably inserted into the recess 22 of the end support 20A about an axis along the projecting direction of the projecting portion 16 . Therefore, the projecting portion 16 is inserted into the recess 22 of the end support 20A, and in a state in which the cross-bar fixing member 10 is temporarily fixed to the end support 20A, the cross-bar fixing member 10 (and its insertion recess 12) is inserted. 25) can be rotated. As a result, the angle of inclination of the cross bar fixing member 10 (and the cross bar 25 inserted into the insertion recess 12 thereof) with respect to the end post 20A can be finely adjusted. Further, as described above, the horizontal rail fixing member 10 can be fixed to the end strut 20A at an appropriate inclination angle according to the inclination angle of the horizontal rail 25 (handrail 6).

In addition, in this embodiment, the projecting portion 16 is provided so as to be positioned at the widthwise central portion of the horizontal beam fixing member 10, and the end surface 14a of the second end portion 14 extends in a direction along the projecting direction of the projecting portion 16. It has a protruding curved surface shape in which the central portion in the width direction protrudes most when viewed. Therefore, even when the horizontal rail fixing member 10 having the projecting portion 16 inserted into the concave portion 22 of the end support 20A is tilted and fixed, the projection dimension of the second end portion 14 from the front surface of the end support 20A can be reduced. can be done. In the illustrated example, the second end portion 14 slightly protrudes from the front surface of the end support 20A in a state in which the cross bar fixing member 10 is fixed to the end support 20A in an inclined manner. It is not limited to such a mode. The second end portion 14 may not protrude from the front surface of the end support 20A when the horizontal rail fixing member 10 is fixed to the end support 20A within the range of the inclination angle of the handrail 6 as described above.

Further, the end surface 14a of the second end portion 14 may be formed in a multifaceted shape or in a flat surface instead of being formed in a convex curved surface shape.
Further, instead of the configuration in which the projecting portion 16 is rotatably inserted into the recessed portion 22 of the end support 20A, it may be configured to be non-rotatably inserted into the recessed portion 22 of the end support 20A. In this case, for example, the protruding portion 16 may have a shape of a substantially polygonal column.
Moreover, in the above example, the horizontal beam 25 has a substantially quadrangular prism shape, but it may have a substantially polygonal prism shape other than a square shape or a substantially cylindrical shape. In this case, the insertion recess 12 of the horizontal rail fixing member 10 may be adapted to the shape of the horizontal rail 25 so as to be appropriately deformed.
In the above example, the side surface 21 of the post 20 is provided with the groove-shaped recessed portion 22 , but a hole-shaped recessed portion 22 having a shape corresponding to the projecting portion 16 may be provided. In this case, a configuration may be adopted in which recesses 22 are provided at a plurality of locations on the side surface 21 of the support 20 at intervals in the longitudinal direction. The configuration of each member and each part of the horizontal rail fixing member 10 and the handrail support device 1 having the horizontal rail fixing member 10 according to the present embodiment is merely an example, and various other modifications are possible.
