An engine (44) includes a bolt (164) that can be inserted into a support hole (250) formed in the tensioner (158) and can swingably support the tensioner (158), and a support member (170) that can contact a contact portion (178) of the blade shoe (168) to support the tensioner (158). The bolt (164) is provided in a crankcase (84). The support member (170) is provided on a head cover (130) and supports the tensioner (158) in such a way that the contact portion (178) is slidable.",
