Vehicular operating device
View Patent ↗A vehicular operating device includes an operating member manipulated to swing, a slider slidably fitted in a holding bore, a cam surface positioned in front of the slider, and a helical compression spring pressing the slider into pressure contact with the cam surface. The metal-made slider includes a first outer peripheral surface with a diameter being smaller than an inner diameter of the helical compression spring, and a guide portion with an outer diameter allowing the guide portion to slide along an inner peripheral surface of the holding bore. A resin-made annular spacer having an outer diameter substantially equal to that of the guide portion is fitted between the guide portion and the helical compression spring. The helical compression spring biases the slider through the annular spacer. The annular spacer holds the helical compression spring in a state not contacting the first outer peripheral surface and the guide portion.
1. A vehicular operating device comprising:
an operating member manipulated in a swingable manner;
a slider fitted in a holding bore disposed in the operating member to be slidable in directions to advance and retract therein;
a cam surface positioned in front of the slider in the advancing direction of the slider; and
a helical compression spring pressing the slider into pressure contact with the cam surface,
the slider sliding along the cam surface when the operating member is manipulated to swing,
the slider comprising a metal shaft and including a first outer peripheral surface with a diameter being smaller than an inner diameter of the helical compression spring, and a guide portion with an outer diameter allowing the guide portion to slide along an inner peripheral surface of the holding bore,
the slider further including: an annular spacer made of resin, fitted between the guide portion and the helical compression spring, and having an outer diameter substantially equal to an outer diameter of the guide portion, the helical compression spring biasing the slider with the annular spacer interposed therebetween; and between the first outer peripheral surface and the guide portion, a tapered second outer peripheral surface with a diameter gradually increasing from the first outer peripheral surface forwards,
the annular spacer having a first inner peripheral surface with a diameter allowing the first inner peripheral surface to be fitted along the first outer peripheral surface, a second inner peripheral surface configured to be positioned in front of the first inner peripheral surface and to be flared to have a diameter larger than the diameter of the first inner peripheral surface, and a contact portion coming into contact with the second outer peripheral surface of the slider, the contact portion being positioned at a boundary between the first inner peripheral surface and the second inner peripheral surface; and
the annular spacer holding the helical compression spring in a state not contacting the first outer peripheral surface and the guide portion of the slider.
2. The vehicular operating device according to claim 1 , wherein the slider further includes a third outer peripheral surface adjacently positioned in front of the second outer peripheral surface, and
the annular spacer further includes a third inner peripheral surface adjacently positioned in front of the second inner peripheral surface, the third inner peripheral surface having a diameter substantially equal to a diameter of the third outer peripheral surface.
3. The vehicular operating device according to claim 2 , wherein a gap is formed between the slider and the annular spacer, and a lubricant is applied to the gap.
