Document Type and Number:
WIPO Patent Application WO/2021/171888
Kind Code:
A1
Abstract:
A forward-reverse switching lever (12) comprises two members: an upper lever member (12A) and a lower lever member (12B). The upper lever member (12A) has a rotating shaft (121) rotatably supported to an upper housing (11A), and is attached to the upper housing (11A) from above. The lower lever member (12B) is attached to the rotating shaft (121) from beneath the upper housing (11A). An O-ring (16) is fitted around the rotating shaft (121), and disposed with the entire perimeter thereof sandwiched between the upper lever member (12A) and the upper housing (11A). The lower lever member (12B) is fixedly attached to the rotating shaft (121), and defines the distance between the upper lever member (12A) and the upper housing (11A), thereby applying pressing force in an axial direction to the entire perimeter of the O-ring (16).
