Abstract
A shift lever apparatus includes a shift lever including a pivot portion and a stick portion formed so as to extend in a vertical direction from the pivot portion, a base member including a shift lever supporting portion and a shift direction and a positioning member for applying a biasing force to the shift lever, and the positioning member having a first elastic member for pressing the shift lever, a second elastic member whose spring constant is smaller than that of the first elastic member and a second elastic member compressed amount regulating member for regulating the second elastic member to be compressed by a predetermined compressed amount so that a length of the second elastic member is a predetermined length.
Claims10
A shift lever apparatus comprising:
- a shift lever including a pivot portion and a stick portion formed so as to extend in a vertical direction from the pivot portion;
- a base member including
- a shift lever supporting portion for supporting the pivot portion so that the shift lever is pivotable in a select direction and a shift direction and a positioning member for applying a biasing force to the shift lever so as to pivot in one direction and the other direction of the select direction so that the shift lever is balanced at a neutral position of the select direction;
- and
- the positioning member including a first elastic member for pressing the shift lever in a manner where one portion of the positioning member contacts the shift lever and for compressing/extending in accordance with the pivotal movement of the shift lever in the select direction, a second elastic member whose spring constant is smaller than that of the first elastic member and provided so as to be in line with the first elastic member, and a second elastic member compressed amount regulating member for regulating the second elastic member to be compressed by a predetermined compressed amount so that a length of the second elastic member is a predetermined length.
A shift lever apparatus comprising:
- a shift lever including a pivot portion, a connecting portion connectable to a transmission, and a stick portion, the stick portion extending in a vertical direction from the pivot portion;
- and
- a base member, the base member comprising:
- a shift lever supporting portion in which is received the pivot portion of the shift lever so that the shift lever is pivotally supported for pivoting movement in a select direction and a shift direction;
- a positioning member which applies a biasing force to the shift lever to pivot the shift lever in one direction and an other direction of the select direction so that the shift lever is balanced at a neutral position of the select direction;
- the positioning member including a first elastic member which presses a portion of the positioning member into contact with the shift lever and which compresses/extends during the pivoting movement of the shift lever in the select direction;
- the positioning member including a second elastic member aligned with the first elastic member and possessing a smaller spring constant than the spring constant of the first elastic member;
- the positioning member including a second elastic member compressed amount regulating member which regulates compression of the second elastic member so the second elastic member is compressed when the shift lever is biased to the neutral position, vibrations transmitted from the transmission to the shift lever apparatus and causing vibration of the first elastic member are absorbed by the compressed second elastic member which possesses the smaller spring constant to inhibit vibration of the shift lever.
