Abstract

A shift device includes a housing and a shift lever having a cylindrical shaft portion with a proximal end pivotably supported inside the housing, shaft portion elongated holes extending through a shaft portion peripheral wall and elongated in a shaft portion longitudinal direction, a shift knob fixed to a shaft portion distal end, a detent pin inserted through the elongated holes where both ends of the pin protrude from the elongated holes, and a detent rod inserted in the shaft portion, the rod transmitting operating force of an operating button in the knob to the pin. The pin has a fitting protrusion protruded toward the rod. The rod has a fitting hole at its end. The protrusion is fitted in the fitting hole. A retaining pawl engaged with an engaging recess provided in the pin or engaged with one of the elongated holes is provided at the rod end.

First claim

What is claimed is:

1. A shift device for a vehicle, the shift device comprising:
a housing; and
a shift lever including
a cylindrical shaft portion of which a proximal end is pivotably supported inside the housing, the cylindrical shaft portion having elongated holes that extend through a peripheral wall of the cylindrical shaft portion and that are elongated in a longitudinal direction of the cylindrical shaft portion,
a shift knob fixed to a distal end of the cylindrical shaft portion,
a detent pin inserted through the elongated holes in a state where both ends of the detent pin protrude from the corresponding elongated holes, and
a detent rod inserted in the cylindrical shaft portion, the detent rod being configured to transmit operating force of an operating button provided in the shift knob to the detent pin, wherein

the detent pin has a fitting protrusion protruded toward the detent rod, the detent rod has a fitting hole at its end, and the fitting protrusion is fitted in the fitting hole,
a retaining pawl that is engaged with an engaging recess provided in the detent pin or engaged with one of the elongated holes is provided at the end of the detent rod, and
in an assembled state, radial movement of the retaining pawl is restricted between the fitting protrusion and the cylindrical shaft portion, and disengagement of the retaining pawl is blocked.

2. The shift device according to claim 1 , wherein
the shift lever further includes a spring, and
the detent pin is constantly urged by the spring toward the detent rod.

3. The shift device according to claim 1 , wherein
the retaining pawl includes an elastically deformable neck and an inward latch pawl that protrudes from a distal end of the neck toward the fitting protrusion and that is hooked to the engaging recess, and
in the assembled state, movement of the inward latch pawl toward the cylindrical shaft portion is restricted between the fitting protrusion and the cylindrical shaft portion, and disengagement of the inward latch pawl is blocked.

4. The shift device according to claim 3 , wherein
a plurality of the retaining pawls are provided, and the retaining pawls are respectively engaged with a plurality of the engaging recesses.

5. The shift device according to claim 1 , wherein
the retaining pawl includes an elastically deformable neck and an outward latch pawl that protrudes from a distal end of the neck toward the cylindrical shaft portion and that is hooked to one of the elongated holes, and
in the assembled state, movement of the outward latch pawl toward the fitting protrusion is restricted between the fitting protrusion and the cylindrical shaft portion, and disengagement of the outward latch pawl is blocked.

6. The shift device according to claim 5 , wherein
a plurality of the retaining pawls are provided, and the retaining pawls are respectively engaged with the elongated holes.
