(42) The plurality of first intermediate sections 506 of the first bracket 502 are connected between the first supporting section 508 and the second supporting section 510. The first supporting section 508 of the first bracket 502 and the first rail portion 30a of the rail member 22 are able to support each other. A longitudinal supporting portion 503 of the first bracket 502 and the first wall portion 520a of the reinforcing member 500 are able to support each other. Preferably, the second supporting section 510 of the first bracket 502 and the first wall portion 520a of the reinforcing member 500 are able to support each other, and the plurality of first intermediate sections 506 are extended into the space 522 of the first wall portion 520a of the reinforcing member 500, to further improve the structural strength of the reinforcing member 500 and the rail member 22.

(43) The plurality of second intermediate sections 514 of the first bracket 502 are connected between the third supporting section 516 and the fourth supporting section 518. The third supporting section 516 of the first bracket 502 and the second rail portion 30b and the rail member 22 are able to support each other. The longitudinal supporting portion 503 of the first bracket 502 and the second wall portion 520b of the reinforcing member 500 are able to support each other. Preferably, the fourth supporting section 518 of the first bracket 502 and the second wall portion 520b of the reinforcing member 500 are able to support each other, and the plurality of second intermediate sections 514 are extended into the space 524 of the second wall portion 520b of the reinforcing member 500, to further improved the structural strength of the reinforcing member 500 and the rail member 22.

(44) According to the above arrangement, the reinforcing member 500, the first bracket 502 and the rail member 22 of the fifth embodiment of the present invention are able to support each other, such that the structural strength of the slide rail mechanism are also improved.

(45) As shown in FIG. 10, FIG. 10 is a cross-sectional view illustrating the rail member 22, the reinforcing member 500 and a first bracket 600 of the slide rail mechanism according to a sixth embodiment of the present invention. The difference between the slide rail mechanism of the sixth embodiment and the slide rail mechanisms of the fifth embodiment is that: a first supporting portion 602 of the first bracket 600 includes a first bending section 604, and the first bending section 604 and the lateral side of the first rail portion 30a of the rail member 22 are able to support each other. A second supporting portion 606 of the first bracket 600 includes a second bending section 608, and the second bending section 608 and the lateral side of the second rail portion 30b of the rail member 22 are able to support each other.

(46) According to above arrangement, compared to the fifth embodiment of the present invention, the first bracket 600 of the sixth embodiment and the lateral side of the first rail portion 30a of the rail member 22 are able to support each other through the first banding section 604, and the first bracket 600 and the lateral side of the second rail portion 30b of the rail member 22 are able to support each other through the second bending section 608. As such, the support reliability of the rail member 22, the first bracket 600 and the reinforcing member 500 is improved, and the structural strength of the slide rail mechanism is also improved.

(47) Compared to the prior art, the slide rail mechanisms according to all embodiments of the present invention have advantages over the prior art by the following perspectives (hereinafter, taking the first embodiment as an example):

(48) 1. When the first bracket 24 is moved to an arbitrary position (such as the first position P1 or the second position P2), the first bracket 24, the rail member 22 and the reinforcing member 26 are able to support each other.

(49) 2. When the first bracket 24 is moved to an arbitrary position, the first supporting portion 34a of the first bracket 24 and the first rail portion 30a of the rail member 22 are able to support each other. The second supporting portion 34b of the first bracket 24 and the second rail portion 30b of the rail member 22 are able to support each other, and the reinforcing member 26, the longitudinal supporting portion 36 of the first bracket 24 and the longitudinal body 32 of the rail member 22 are able to support each other. According to above arrangement, the structural strength of the slide rail mechanism can be improved.

(50) Those skilled in the art will readily observe that numerous modifications and alterations of the device and method may be made while retaining the teachings of the invention. Accordingly, the above disclosure should be construed as limited only by the metes and bounds of the appended claims.
