TENSIONER
Document Type and Number:
WIPO Patent Application WO/2016/021739
Kind Code:
A1
Abstract:
This tensioner (10) is provided with: a shaft part (32) in which recesses (32D) to be engaged are formed along the axial direction; and a slide (34) which surrounds a portion of the shaft part (32) while the shaft part (32) is in a state of being loosely inserted therein, and which is moved along the shaft part (32) towards one side in the axial direction by the impelling force from a coil spring (36). Tips (38) provided with engagement protrusions (38E) for engaging with the recesses (32D) to be engaged of the shaft part (32) are provided between the shaft part (32) and the slide (34). When the slide (34) is moved towards the one side, the tips (38) are moved towards the one side in conjunction with the slide (34). Furthermore, the engagement protrusions (38E) of the tips (38) engage with the recesses (32D) to be engaged, and, as a result, movement of the slide (34) towards the other side in the axial direction is restricted.
