An inclination angle ([theta]1) of the first wall surface (11a) with respect to a first normal (12a) to a contact surface passing the first edge (10a) is greater than an inclination angle ([theta]2) of a second wall surface (22b) with respect to a second normal (23b) to the contact surface passing the second edge (21b).",
