In the sipes, protrusions are formed on a first sipe wall surface of mutually opposing sipe wall surfaces and recesses that engage with the protrusions are formed on a second sipe wall surface. Collapse of portions of the block sandwiched by the sipes is suppressed due to engagement of the protrusions and the recesses.
