[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a shift lever device that has an improved support structure for a link lever that is rotated in conjunction with a shift lever.

[Prior art] Conventionally, the structure of the support point of a link lever that rotates in conjunction with a shift lever is such that a shaft body is press-fitted into a predetermined position via a bushing into the inner circumference of a cylindrical body that is fixed to a bracket by welding or the like. The linkage lever was inserted rotatably through the shaft, and the linkage lever was fixed to the shaft body with a screw, so that a predetermined rotational resistance was generated in the linkage lever. However, in such a conventional structure, the inner diameter and length of the cylindrical body and the outer diameter and length of the shaft body had to be dimensionally controlled, making manufacturing cumbersome.

A threaded portion 6b passes through a through hole 8 of the bracket 2 and is fixed to the bracket 2 with a nut 10 via a spring washer 9. The cylinder body 4 of the shift lever 3 has a plastic bush 1.
It is rotatably supported around the outer periphery of the shaft portion 6a of the bolt 6 via 1 and 11. Reference numeral 12 denotes a link lever with pins 13 and 14 protruding from both upper and lower ends. An insertion hole 16 is bored in the portion. On the other hand, 17 is a cylindrical part formed by burring on the side surface of the bracket 2 to have a predetermined outer diameter and a predetermined length, and a washer that can be elastically deformed in the axial direction of the cylindrical part 17 is attached to the outer periphery of the cylindrical part 17. Aru Nami Washiya 18
and a flat washer 19 are inserted, respectively, and furthermore, the insertion hole 16 in the intermediate part of the linking lever 12 is rotatably inserted into the outer periphery of this cylindrical part 17 via a plastic bush 20. The above button 2
0 is equipped with a cylindrical portion 20a and a flange 20b formed at one end thereof, and the cylindrical portion 20a is fitted into the insertion hole 16 formed in the link lever 12, and the flange The part 20b is the cooperation lever 1
2, it is addressed to the side opposite to bracket 2. Reference numeral 21 denotes a bolt as a fixing device inserted into the cylindrical portion 17 from the tip side with the spring washer 22 and flat washer 23 inserted into the lower part of the neck. A nut 24 is screwed and secured, and the link lever 12 is positioned and held on the outer periphery of the cylindrical portion 17 by these bolts 21 and nuts 24.

Now, 25 is an indicator housing fixed to the plate 1 with screws, the upper surface 25a of which forms an arc-shaped surface centered on the cylinder 4, and the shift lever 3 passes through the center of the upper surface 25a. A rectangular through hole 26 is provided. Further, on both sides of this through hole 26, through holes 27 and 28 parallel to the through hole 26 are provided. 29
2 is an indicator casing disposed along the inside of the upper surface 25a of the indicator housing 25, the part facing the through hole 27 is depressed to form a lamp housing 30, and the lamp 3 is inserted here.
1 is disposed, and the through hole 28 is directly closed. 32 is an indicator plate that covers the through hole 27, and has "P, R, N, D,
The display characters ``2, L'' are displayed using cut-out printing, etc. 33 is a guide recess formed in the upper surface of the indicator casing 29 so as to face between the through holes 26 and 27;
and 28 are guide grooves formed on the upper surface of the indicator casing 29 so as to face each other. 35 is a slide cover disposed to cover the through hole 26, and the shift lever 3 is located in the center of the slide cover.
A cylindrical portion 35a that penetrates is integrally molded,
When the shift lever 3 is rotated, it is slid integrally. Reference numeral 36 denotes a pointer portion which is provided at the center of one side end of the slide cover 35 and protrudes laterally through a hanging portion 36a,
This is guided by the upper surface of the guide recess 33 and faces the lower surface of the indicator plate 32.

Therefore, the hanging portion 36a is inserted into the through hole of the guide recess 33 when the shift lever 3 receives a displacement force in the direction of arrow A perpendicular to the normal operation direction and a displacement force in the direction of the arrow A acts on the slide cover 35. 26 side, prevents the slide cover 35 from creating a gap with the periphery of the through hole 26, and the regulating protrusion 37 prevents the shift lever 3 from moving in the normal operating direction. When the slide cover 35 receives a displacement force in the direction of the arrow B at right angles and a displacement force in the direction of the arrow B acts on the slide cover 35, the guide groove portion 3
This prevents the slide cover 35 from creating a gap with the periphery of the through hole 26 by catching on the rising portion 34a located on the side of the through hole 26 of No. When the slide cover 35 cannot be made sufficiently large compared to the above, the slide cover 35 is prevented from being displaced in the direction of the arrow A or the direction of the arrow B, thereby preventing the slide cover 35 from creating a gap with the periphery of the through hole 36. I'm trying to get it.

According to the above configuration, the support point of the link lever 12 can be formed by burring, so the structure is simpler and the manufacturing process is easier than in the conventional configuration in which the shaft body is supported by a bearing sleeve. By the way, when forming the cylindrical part 17 by burring in this way,
In particular, the height of the cylindrical portion 17 tends to vary, albeit slightly. In view of this point, in this proposal,
Pass the bolt 21 through the cylindrical portion 17 and tighten the nut 24.
The link lever 12 is tightened toward the bracket 2, and a corrugated washer 18 that is elastically deformed in the axial direction of the cylindrical portion 17 is disposed between the link lever 12 and the bracket 2. As a result, even if an error occurs in the height dimension of the cylindrical portion 17 during burring, the dimensional error can be absorbed by the amount of deformation of the corrugated washer 18. Precision is not required and manufacturing is easy. Furthermore, the insertion hole 16 of the circular lever 12 is inherently prone to wobbling unless very strict dimensional control is performed; Button 2 equipped with a flange 20b
0 is provided in the insertion hole 16 of the circular lever 12, the rattling of the link lever 12 can be effectively suppressed by the flange 20b of the bushing 20 without strict dimensional control of the insertion hole 16. be able to.

[Effects of the invention] As is clear from the above explanation, the invention can reduce the amount of dimensional control during processing.
