Patent number: 11873859Abstract: A clamper mechanism for a motion guide device includes a clamper block having tapered faces, clamper rolling elements arranged between the tapered faces and both left and right side faces of a track member, and a clamper rolling element holder attached to the clamper block with an interposition of an elastic member. When an elastic force exerted by the elastic member acts in a direction in which the clamper block and the clamper rolling element holder are separated from each other, the clamper rolling elements bite the tapered faces to bring the clamper block into a state restrained to the track member. When an external force against the elastic force exerted by the elastic member acts, the clamper rolling elements are brought into a free state within the tapered faces to bring the clamper block into a state not restrained to the track member to exert a stable clamping force.Type: GrantFiled: April 28, 2020Date of Patent: January 16, 2024Assignee: THK CO., LTD.Inventors: Yoshinori Murakami, Reiji Abe, Tadashi Matsuhira, Yoshiro Oishi, Hiroaki Mochizuki, Hajime Fukushima, Hiroomi Kuribayashi, Akito Kaneko
