And an operating force transmission mechanism 7 for transmitting the operating force applied to the latch claw 4. The front plate 33 mounted on the front surface of the back plate 32 has an opening 5a of the puller frame 5.
Is provided with a window 33a for opening the outside.

As shown in FIGS. 2 to 4, the pull tab frame 5 is of a casing type having a front opening, and is integrally formed of synthetic resin. Specifically, the pull tab frame 5 is a horizontally long housing having left and right side walls 51, 52, a bottom wall 53, a flat wall 54, and a ceiling wall 55.
5 is formed only on the front edge. A short mounting rod 56 is integrally projected from one side wall 51, and a long mounting rod 57 is extended from the other side wall 52. The pull bar frame 5 is attached to the mounting plate 57 by the back plate 32.
There are provided screw holes 56a and 57a for attaching to. In addition, as shown in FIG. 5, a cylindrical portion 51c having a cavity 51b that opens forward and backward is integrally formed at a rear edge 51a of an upper end portion of one side wall 51, and a hole 8 that supports a spindle 61 of the operating lever 6 is formed. The rear edge 51a of the one side wall 51 is formed at a position that opens into the cavity 51b. Further, as shown in FIG. 6 and FIG. 7, the tubular portion 5 having a cavity 52b opened at the other side wall portion 52 of the pull frame 5 in the front-rear direction.
2c is integrally formed, the notch recess 9 is formed at the rear end of the tubular portion 52c, and cantilevered forward at a position behind the tubular portion 52c and visible from the front through the cavity 52b. An elastic beam-shaped retaining member 10 that protrudes to the outside is provided. That is, the cavity 52 provided in the molding die
The stopper member 1 is provided at the tip of the protruding portion for forming b.
The free end portion of 0 can be molded.

The operation lever 6 is a plate-like member having a shaft holding portion 62 having a C-shaped cross section at the base end 6b, and is made of synthetic resin. The shaft holding portion 62 serves to support the support shaft 61. It is held so that it can rotate together. That is, the wavy deformation portions 61a are provided at two locations on the support shaft 61. Then, the support shaft 61 is attached to the shaft holding portion 62 with the wavy bent portion 61a left outside.
By inserting the corrugated deformation portion 61a into the shaft holding portion 62 by using the elastic deformation of the shaft holding portion 62 by forcibly rotating the support shaft 61, the support shaft 61 is inserted. Can be attached to the operation lever 6. The operation lever 6 is attached to the pull tab frame 5 by first inserting the one end of the support shaft 61 into the hole 8 provided in the one side wall 51 of the pull frame 5 and positioning the operation lever 6 inside the pull frame 5. The other end side of 61 is the retaining member 10
Is elastically deformed downward to engage with the notch recess 9. The other end of the support shaft 61 extends laterally, and the extending end is bent downward to form a drooping bent portion 61b. Drooping bend 6 of the support shaft 61
1b is guided by a guide wall 57b protruding from the mounting rod 57.

The operating force transmission mechanism 7 is formed by extending a rotary shaft 71 holding the base end of the latch claw 4 upward and bending the extending end horizontally to form a horizontal bent portion 71b.
The horizontal bent portion 71b is engaged with the depending bent portion 61b provided on the support shaft 61 of the operation lever 6 in an orthogonal state. Then, the latch claw 4 is urged to rotate outward by a spring (not shown), and the urging force pushes the horizontal bent portion 71b against the drooped bent portion 61b.

With such a structure, when a hand is inserted into the opening 5a of the puller frame 5 and a pulling operation is performed toward the front, the operation lever 6 is rotated forward. As a result, the support shaft 61 rotates together with the operation lever 6, and the depending bent portion 61b moves forward, so that the rotation shaft 71
The horizontal bent portion 71b is pressed forward to rotate the latch claw 4 inward. The latch can be released in this way, but this one has one end of the support shaft 61 inserted into the hole 8 to be supported, and the other end engages with the notch recess 9 opened rearward. Therefore, even if the tip portion 6a of the operation lever 6 should be operated, even if the vicinity of the base end portion 6b is accidentally pulled toward you, the support shaft 61 may come off from the bearing position. Absent.

Further, the hole 8, the notch recess 9 and the retaining member 1 are provided.
If 0 is formed in the above-described form, when integrally molding with an injection molding machine, all of these holes 8, cutout recesses 9 and retaining members 10 are pulled using a normal die that is divided only in the front and rear. It can be formed integrally with the frame 5.

The overall shapes of the pull frame and the operating lever are not limited to those shown in the illustrated embodiment, and various modifications can be made without departing from the spirit of the present invention.

The present invention is not limited to drawers of wagons, but can be similarly applied to drawers of desk sleeves, storage furniture, and the like.
