2 are integrally formed. The umbrella portion 62 is formed in a funnel shape, and a discharge port 64 is formed on the funnel-shaped bottom surface, and a drain pipe 66 is connected to the discharge port 64.

In this shift lever device 60, even if liquid such as drinking water spills from the vehicle interior and enters the inside of the gap between the guide hole 34 (cover slide 36) and the shift lever 12, it spills from above. The liquid flowing down the shift lever 12 is received by the funnel-shaped umbrella portion 62, and is further discharged from the discharge port 64 to the outside of the apparatus through the drainage pipe 66. Therefore, the support shaft portion of the shift lever 60 (the retainer 14 and the shaft 16
Etc.) and the grooved pin 18 will not be flooded. Therefore, the functions and operations of the respective parts are not hindered, and no inconvenience occurs. Further, in this way, simple waterproofing can be realized with an extremely simple structure. (Fourth Embodiment) FIG. 5 is a perspective view of a main portion of a shift lever device 70 according to a fourth embodiment of the present invention.

In the shift lever device 70, a dam portion 72 as a waterproof means is integrally formed at the longitudinal middle portion of the grooved pin 18. The dam portion 72 has a brim shape and is provided integrally with the grooved pin 18. Therefore, the weir 72 prevents the liquid from dripping from the shift lever 12 to the tip of the grooved pin 18.

In this shift lever device 70, the liquid that has spilled from the upper side and is transmitted to the shift lever 12 is received by the dam portion 72 formed integrally with the grooved pin 18, and drips toward the tip end side of the grooved pin 18. The flow is blocked. Therefore, the grooved pin 18
The other shift lock parts, etc. corresponding to the above will not be flooded. Therefore, the functions and operations of the respective parts are not hindered, and no inconvenience occurs. Further, in this way, simple waterproofing can be realized with an extremely simple structure. (Fifth Embodiment) FIG. 6 is a perspective view of a main portion of a shift lever device 80 according to a fifth embodiment of the present invention.

In the shift lever device 80, a weir portion 82 as a waterproof means is integrally formed at the longitudinal middle portion of the grooved pin 18. The weir portion 82 is the grooved pin 1
The periphery of 8 is a concave groove cut out in a ring shape.

Also in this shift lever device 80, the liquid that has spilled down from the upper side and is transmitted to the shift lever 12 is received by the dam portion 82 formed on the grooved pin 18 (is retained in the dam portion 82), and the grooved pin 18 is retained. Is prevented from flowing toward the tip end side of the. Therefore, other shift lock parts and the like corresponding to the grooved pins 18 will not be flooded. Therefore, the functions and operations of the respective parts are not hindered, and no inconvenience occurs. Further, in this way, simple waterproofing can be realized with an extremely simple structure. (Sixth Embodiment) FIG. 7 shows a perspective view of a main portion of a shift lever device 90 according to a sixth embodiment of the present invention.

The shift lever device 90 has a cover slide 92. The cover slide 92 is formed in a V shape (downward concave shape) when viewed from the front.
The cover slide 92 receives the liquid such as drinking water spilling from above, guides and discharges it in the operation moving direction of the shift lever 12 (that is, the longitudinal direction of the guide hole 34), and then to the guide rail portion 38 of the housing 32. It has the role of blocking the flow of water.

In the shift lever device 90, if liquid such as drinking water spills from the vehicle compartment, the spilled liquid tries to enter the inside through the guide hole 34 formed in the housing 32. Here, since the cover slide 92 provided in the guide hole 34 is formed in a V shape (downward concave shape) in a front view, the spilled liquid is guided and discharged in the operation moving direction of the shift lever 12. , The sliding portion of the cover slide 92 (ie, the housing 32
Does not enter the guide rail portion 38). Therefore, the sliding operation of the cover slide 92, that is, the shift operation of the shift lever 12 is not hindered, and a good operation feeling can be maintained.
