Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Field of Industrial Application) The present invention relates to an improvement of a shim member for adjusting a gap between two members fitted to a shaft body.

(Prior Art) Generally, in assembling an apparatus or the like, a thin plate-shaped shim member is used to remove a gap between two members, for example, an unwanted play (backlash). In this method, shim members having various thicknesses are prepared in advance, the shim members are sequentially inserted into the gap, and the optimum gap or combination is selected to obtain the desired gap. However, an annular shim member such as a washer is used to adjust the gap between the two members fitted to the shaft body. Therefore, since the annular shim member is used in a state of being fitted to the shaft body, when the shim member is replaced, the shim member must be detached from the shaft body and inserted and replaced each time. There was an inconvenience that it took time and effort.

(Problems to be Solved by the Invention) As described above, since the annular shim member is used to adjust the gap between the two members fitted to the shaft body, it is necessary to remove the fitting member from the shaft body at the time of replacement. However, there was an inconvenience that the workability was extremely poor.

The present invention has been made to solve the above-described inconvenience, and an object of the present invention is to provide a shim member that is easy to insert and remove between members fitted to a shaft body and has good workability.

[Structure of the Invention] (Means for Solving the Problems) In order to achieve the above-mentioned object, the shim member of the present invention has an insertion notch in which the shaft body can be inserted and removed from an open one end side, and A shim portion inserted between the two fitted members, a rotation preventing portion that is bent and connected to the shim portion and engages with one of the members to prevent rotation, and an end portion of the rotation preventing portion is bent. And an engaging and holding portion which is provided in parallel with the shim portion, and which includes a pair of elastically deformable holding pieces for holding the shaft body by inserting the shaft body into the insertable and removable insertion notch. Is characterized by.

(Operation) The shim member of the present invention is provided with an insertion notch which is insertable and removable from the side of the shaft body to facilitate insertion and removal of the shim part, and is provided with a rotation preventing part. Since the gripping piece that grips the body (including the part that is integral with the shaft body) is provided to prevent the shaft body from coming off, the workability is extremely good and the clearance adjustment is similar to that of the annular shim member. It has a function.

(Examples) Hereinafter, details of the shim member of the present invention will be described with reference to the illustrated examples.

The shim member of this embodiment is applied to a shift select mechanism of a vehicle. Therefore, first, the shift select mechanism will be briefly described with reference to FIG. 1 and FIG. 2. Reference numeral 1 is a bracket, which is fixed to a body (not shown), has an opening 3 on an upper surface 2, and has side walls 4, 4 Axial holes 5, 5 are provided in the. A shaft body 7 made of a bolt is inserted and attached to the shaft holes 5, 5. Further, a lower sleeve 10 of a sleeve member 12 in which a lower sleeve 10 and an upper sleeve 11 are integrally formed in a three-dimensional tolerance shape at right angles to each other is rotatably fitted to the outer side of the shaft body 7.

On the other hand, a substantially U-shaped yoke 15 provided at the lower end of the operating lever 14 is inserted through the opening 3, and the yoke 15 is provided with shaft support holes 16 and 16. A shaft body 18 including a bolt 17 is inserted and attached.

The upper sleeve 11 is rotatably fitted on the outside of the shaft body 18.

The shift select mechanism is configured as described above,
The operating lever 14 is rotatable in the direction of arrow 21 about the axis 18a, and is also rotatable in the direction of arrow 22 about the axis 7a.

The shim member 26 of the present invention is the end surface 11 of the upper sleeve 11.
It is inserted between a and the inner surface 15a of the yoke 15.

Next, the shim member 26 of the present invention will be described with reference to FIGS.

The shim member 26 includes a shim portion 45, a rotation preventing portion 46, and an engagement holding portion 47.

The shim portion 45 is provided with an insertion notch 48, which is formed with the same width (diameter) from one end side 49, and the shaft body 18 can be inserted and removed from the side.

The rotation preventing portion 46 is formed by bending the other end side 51 of the shim portion 45 at a right angle.

The engagement holding portion 47 is provided in parallel with the shim portion 45 by bending the end portion of the rotation preventing portion 46, and is composed of a pair of holding pieces 52, 52 that are easily elastically displaced. The sandwiching pieces 52, 52 elastically displace and sandwich the head 17 of the shaft body 18 at the same time when the shaft body 18 is inserted into the insertion notch 48, and prevent the shim member 26 from separating from the shaft body 18. Works for.

As shown in FIGS. 4 and 5, the shim member 26 includes a back surface 15a of the yoke 15 and an end surface 11a of the upper sleeve 11.
The rotation preventing portion 46 is inserted between the rotation preventing portion 46 and the side surface 15b of the yoke 15 to prevent rotation.

Further, at the same time when the insertion notch 48 of the shim portion 45 is engaged with the shaft body 18, the clamping pieces 52, 52 elastically clamp the head 17 of the shaft body 18 from both sides, so that the shim member 26 is removed from the shaft body 18. Withdrawal is effectively prevented.

When the shim member 26 is replaced with one having a different thickness, if the shim member 26 is pulled, the holding pieces 52, 52 of the engagement holding portion 47 are easily elastically deformed and the shim member 26 is moved to the shaft body 18. Since the shaft 18 and the fitting members such as the upper sleeve 11 and the yoke 15 are not required to be disassembled at all, workability is extremely excellent.

Therefore, according to the present invention, there is no need to process a screw or a screw hole for attaching the shim member 26, and the attachment and detachment of the shim member 26 can be performed with a single touch without using a tool, thus improving workability and workability. It is extremely advantageous in terms of economy.

It should be noted that the above embodiment has been described for the case of being applied to the shift select mechanism of the vehicle, but the present invention is not limited to this, and is also applicable to adjustment of a gap between two members fitted to other shaft bodies. Can be applied.

In addition, although one shim member is used in the above embodiment, a plurality of shim members may be used in combination.

(Effects of the Invention) As described in detail above, the shim member of the present invention can be inserted and removed from the side of the shaft body without using a tool, and moreover, it is prevented from being undesirably separated by the elastic force. No need to machine screws and screw holes, and simply replace the shim member by inserting and pulling it out, so workability is extremely excellent.
