Patent number: 9797488Abstract: 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.Type: GrantFiled: October 7, 2015Date of Patent: October 24, 2017Assignee: APLS ELECTRIC CO., LTD.Inventors: Tsuyoshi Kikuchi, Seishi Takahashi

Patent number: 9227560Abstract: A cancelling drive member includes a biasing cam portion having a first biasing contact portion and a second biasing contact portion formed therein. A deflectable spring member that biases the cancelling drive member forward is provided. If the cancelling drive member rotates, an elastic pressure portion of the deflectable spring member is brought into contact with the first biasing contact portion. Thus, a forward biasing force and a returning force for rotation are effectively given from the deflectable spring member to the cancelling drive member.Type: GrantFiled: July 10, 2014Date of Patent: January 5, 2016Assignee: Alps Electric Co., Ltd.Inventors: Tsuyoshi Kikuchi, Yu Masuya, Nobuyuki Tanabe

Publication number: 20150332876Abstract: A multi-point switching apparatus includes a continuous common pattern formed on a contact circuit board, equally spaced to-be-switched patterns, and a slider that is brought into sliding contact with both the common pattern and one to-be-switched pattern. The slider is moved to make a switchover in succession. The slider includes a first sliding part and second sliding part that are elastically deformable individually. Each to-be-switched pattern includes a first pattern part placed so as to be brought into sliding contact with the first sliding part and a second pattern part placed so as to be brought into sliding contact with the second sliding part. The first pattern part and second pattern part are electrically connected to each other for each of the to-be-switched patterns. While any of the first sliding part and second sliding part is in a space, the other is in sliding contact with the to-be-switched pattern.Type: ApplicationFiled: May 12, 2015Publication date: November 19, 2015Inventor: Tsuyoshi Kikuchi
