Patent number: 11738719Abstract: A connecting structure of a wiper arm includes a connecting shaft provided on a wiper arm and a snap-fit provided on a wiper blade. The snap-fit includes a pair of claws defining a groove that can be engaged with the connecting shaft. A slit defined by inner walls facing each other is provided on both sides of the pair of claws in a longitudinal direction of the wiper blade. A first protrusion protruding toward inside of the slit is provided on one of the inner walls, and a second protrusion protruding toward inside of the slit is provided on the other of the inner walls. The first and second protrusions are arranged offset from each other in a direction along an axial direction of the connecting shaft.Type: GrantFiled: February 23, 2022Date of Patent: August 29, 2023Assignee: MITSUBA CorporationInventors: Hiroki Kashihara, Tomoya Nishikawa

Patent number: 10625714Abstract: Base end sides of washer tubes 44, 45 are arranged in an axial direction of a swinging shaft PS at one end portion of an arm head 40, and they are drawn out from a head side pipe housing portion 41a so as to curve toward a side opposite to a shaft fixing portion 42 side. Each of the washer tubes 44, 45 is wound around the shaft fixing portion 42 during swinging of the arm head 40 without applying any load to the swinging shaft PS. No tension acts on each of the washer tubes 44, 45, and each of the washer tubes 44, 45 is not rubbed against the shaft fixing portion 42. Therefore, deterioration of the washer tubes 44, 45 can be suppressed. When the washer tubes 44, 45 are wound around the shaft fixing portion 42, a periphery of the shaft fixing portion 42 is suppressed from swelling outward in a radial direction thereof. This makes it possible to prevent the arm head 40 around the swinging shaft PS from increasing in size.Type: GrantFiled: March 23, 2016Date of Patent: April 21, 2020Assignees: MITSUBA CORPORATION, HONDA MOTOR CO., LTDInventors: Masayuki Shimoyama, Tomoya Nishikawa, Atsuhiro Kuwabara, Yutaka Yamashita, Shin Fujiwara, Hideyuki Koizumi, Takeshi Sasaki, Taisuke Goto, Tatsuya Ohmaru, Yuki Takahashi

Patent number: 10071710Abstract: The swing member (63) to be subjected to swinging drive is integrally provided to the output shaft (56) outside the speed reducer case (52), the speed reducer case (52) is provided with a pair of swing regulating portions (61, 62) which prevents the swing member (63) from being moved beyond the wiping-allowable limit angle (b°) by contacting the swing member (63). As a result, the swing member (63) and the swing regulating portions (61, 62) can collectively form the regulating member (60). As a result, essential components (such as fixing plate) can be omitted from the conventional wiper apparatus. Therefore, the wiper apparatus can be improved in assembly workability, size and weight by reducing the number of components thereof, and provided with a regulating member (60) which prevents the wiper member being moved beyond the wiping-allowable limit angle (b°).Type: GrantFiled: December 25, 2014Date of Patent: September 11, 2018Assignee: Mitsuba CorporationInventors: Masafumi Takimoto, Shin Akimoto, Masaaki Kimura, Takeshi Kanai, Tomoya Nishikawa, Yukiyoshi Iso
